Background: Hydatid cysts, caused by Echinococcus granulosus , are uncommon in the breast but are observed in endemic regions of the Eastern Mediterranean. This study evaluates the diagnosis and treatment of this rare occurrence of breast hydatid cyst and its spontaneous rupture. Case Presentation: A 33-year-old female patient presented to our clinic with a mass in the right breast that had been growing for 9 months and causing intermittent pain. Physical examination revealed a well-defined, firm mass with regular borders and some soft areas. Ultrasonography reported a complicated cyst(?). While awaiting the report of breast magnetic resonance imaging, the patient returned to the hospital because of the discharge of white material from the breast. Examination revealed a laminar membrane from the perforated area. Under sedation, the cyst was evacuated, vesicles were removed, and the cyst cavity was irrigated with 3% saline for drainage. Conclusions: Although breast hydatid cyst is rare, it should be considered in the differential diagnosis, especially in endemic regions. Magnetic resonance imaging and drainage, combined with prophylactic albendazole, represent a safe and effective diagnostic and treatment approach.

Pseudoangiomatous stromal hyperplasia (PASH) is a benign mesenchymal proliferative lesion of the breast. In 2005, only 109 cases have been reported since its initial description in 1986 by Vuitch et al. when it presented in one patient as a palpable breast mass. We retrospectively reviewed data from 2020 to 2023 of patients diagnosed with PASH by surgical excision. Our 13 cases represent one of the most numerous reported from a single institution. All histologic specimens were examined by a single pathologist. All patients had breast masses on imaging or were clinically evident. Eleven of the patients (84.6%) were diagnosed by surgical excision, whilst only two (15.4%) were diagnosed by core needle biopsy. Imaging revealed no strongly distinctive features for PASH. The age of the patients ranged from 25 to 68 years. All but one of the women were premenopausal at the time of diagnosis. This study suggests that PASH is a lesion whose diagnosis is often incidental and the recommended treatment is more commonly surgical., Competing Interests: Declarations.

Background: Primary breast hydatid cyst is an exceedingly rare manifestation of echinococcosis, with an incidence of less than 0.27% among all hydatid cyst cases., Case Report: This report presents a unique case of a 51-year-old multiparous female who initially presented with a painless left breast mass. Initial imaging studies, including ultrasonography and mammography, revealed a 4.5 × 4 cm cyst classified as BI-RADS 3. The cyst was initially managed with fine-needle aspiration and conservative treatment. However, it recurred twice over a six-month period, necessitating surgical excision. Preoperative laboratory work ups revealed eosinophilia, a finding initially overlooked but later recognized as significant. Histopathological examination of the excised specimen confirmed the diagnosis of a hydatid cyst. Post-surgical management included albendazole therapy, regular imaging follow-ups, and patient education on hygiene practices to prevent reinfection., Conclusion: This case highlights the importance of considering parasitic etiologies in the differential diagnosis of breast masses, particularly in endemic regions. It also underscores the value of a multidisciplinary approach in managing such rare cases. The unexpected diagnosis of a primary breast hydatid cyst in this case serves as a reminder of the diverse presentations of echinococcosis and the need for heightened clinical suspicion in atypical breast lesions., Clinical Trial Number: Not applicable., Competing Interests: Declarations.

The nipple-areolar complex (NAC) is an anatomically unique region from which several normal variants and pathologies arise. Understanding its anatomy is crucial for accurate clinical and imaging assessments, aiding with differential diagnosis, and ensuring radiologic-pathologic concordance. Mammography and US are commonly used for NAC evaluation; however, these are susceptible to technical limitations such as tissue superimposition and artifacts, compromising visualization of abnormalities in this area. Although MRI offers higher sensitivity, it is not the initial evaluation modality. A comprehensive clinical inspection is necessary because it may reveal abnormalities not apparent on imaging. This article offers an anatomical approach to the NAC evaluation, simplifying differential diagnoses by reviewing imaging techniques and clinical features of common NAC abnormalities., (© Society of Breast Imaging 2024.

Radial sclerosing lesions (RS, also referred to as "radial scars") and complex sclerosing lesions (CSL) are uncommon breast lesions often grouped together as a single entity in practice. RS/CSL have an incidence of <0.1% to 1% at core needle biopsy (CNB). When detected on CNB, imaging and pathology features must be carefully evaluated to determine appropriate surgical management or imaging follow-up due to potential for malignant upgrade at surgery. Detection of RS/CSL has increased with the advent of tomosynthesis, in which an RS/CSL is typically detected as architectural distortion with or without associated mass with spiculated margins. On US, an RS/CSL is most often occult or manifests as subtle distortion with adjacent cysts. Imaging findings cannot distinguish benign RS/CSL from those upgraded to malignancy at surgery, although larger lesion size may be associated with higher upgrade rates. Histologically, an RS has a central fibroelastotic nidus with entrapped-appearing ducts and proliferative changes at the periphery appearing to radiate from the center; CSL are larger than RS, more disorganized, and typically include multiple patterns of epithelial proliferations, including sclerosing adenosis, sclerosing papillomas, usual ductal hyperplasia, and cysts. RS/CSL with associated atypia at CNB have a 16%to 29% rate of upgrade to malignancy on surgical excision, thus rendering surgical excision essential. Conversely, an RS/CSL without associated atypia, particularly when ≤1 cm in size, has <3% rate of upgrade to malignancy at surgery, allowing consideration of imaging follow-up in lieu of excision. Here, we review recent literature as well as radiology and pathology findings of RS/CSL., (© Society of Breast Imaging 2024. All rights reserved.

Pseudoangiomatous stromal hyperplasia (PASH) is a rare, benign breast lesion characterized by collagen proliferation, often identified as an incidental microscopic finding. Clinically, it may present as a palpable, well-defined breast mass or, in rare instances, as a diffuse, bilateral process leading to significant breast enlargement. We herein report a case of extensive diffuse PASH with short-term recurrence following lesion resection at another hospital. Because of the severity of symptoms, the patient underwent bilateral mastectomy at our facility. This article reviews the clinical, radiologic, and pathologic features of PASH and emphasizes the importance of an accurate preoperative imaging diagnosis for guiding appropriate treatment., Competing Interests: Declaration of conflicting interestThe authors declare that there is no conflict of interest.

A 40-year-old woman admitted for hyponatremia and anasarca due to decompensated cirrhosis after a recent steroid taper developed extremely painful cutaneous breast lesions clinically mimicking cellulitis and inflammatory breast cancer and was biopsy-diagnosed instead with diffuse dermal angiomatosis (DDA) of the breasts, a rare and painful disease that can be a diagnostic chameleon. This case highlights the importance of early surgical consultation and tissue biopsy to correctly diagnose the etiology of severely painful mastitis and prevent prolonged symptomology and repeated administrations of ineffective treatments. Diffuse dermal angiomatosis should be considered when suspected breast cellulitis is refractory to treatment or there is concern for inflammatory breast cancer, especially in pendulous-breasted women with comorbidities that increase susceptibility to local tissue hypoxia., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Coronary artery disease (CAD) continues to be the leading cause of morbidity and mortality in women, contributing to about 20%, or nearly 400,000, of female deaths annually in the United States. Despite their significant burden from CAD, women have been traditionally underrepresented in trials, and therefore, there is still much to be studied regarding the sex-based variations that have been reported regarding the pathophysiology, clinical presentation, efficacy of diagnostic workup, and response to therapy in CAD. Previous studies have reported that breast arterial calcifications, commonly found incidentally on screening mammography, may be associated with risk of CAD; however, there are currently no specific guidelines concerning reporting and quantification practices, as well as further workup recommendations for patients who are found to have vascular calcifications. Thus, the question remains whether breast arterial calcifications can serve as a sex-specific marker for CAD, and whether there is enough evidence to support the use of mammography as a screening tool for CAD in women. In this review, we will summarize the current understanding of cardiovascular disease in women, the existing literature regarding breast arterial calcifications and current reporting practices, and the association of vascular calcifications with CAD risk; based on the collected evidence, we will make a recommendation whether screening mammography and breast arterial calcifications should be used to assess CAD risk, and if so, what additional workup, if any, we recommend in women found to have breast arterial calcifications on imaging., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © 2023 Wolters Kluwer Health, Inc.

Cat scratch disease rarely presents as a breast or axillary mass mimicking carcinoma both clinically and radiologically. Diagnosing breast/axillary cat scratch disease is challenging due to its rarity and nonspecific findings. Here, we reported 2 patients with breast cat scratch disease and reviewed 14 patients with cat scratch disease involving breast/axilla from the past 30 years. It mainly affects women (median age: 48), consistently presenting as axillary lymphadenopathy, and demonstrates ipsilateral breast mass in half of patients (50%, 8/16). The breast mass was most commonly located in the upper outer quadrant (88%, 7/8), indicating the possibility of disease extension from axillary adenopathy. Around half of patients (56%, 9/16) reported cat exposure. Histologically, most patients (93%, 14/15) presented as necrotizing granulomas, with characteristic stellate-shaped necrosis in 5 patients. Although pathologic differential diagnoses between cat scratch disease and cancer are straightforward, distinguishing cat scratch disease from other granulomatous mastitis poses diagnostic challenges. Silver stains should be included in the diagnostic workup panel when highly suspecting cat scratch disease clinically. However, they were only able to highlight the causative microorganism in 54% (7/18) patients, and the gram stain was negative in all 12 tested patients. In contrast, polymerase chain reaction (PCR) for the causative microorganism was consistently positive in all 3 tested patients, while serologic test confirmed diagnosis in 85% (11/13) patients; 1 patient with negative serology showed a positive PCR result. Therefore, upfront PCR tests with or without serologic study should be considered to confirm the diagnosis of cat scratch disease in a timely manner., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: To investigate the clinicopathological features and differential diagnosis of breast angiomatosis. Methods: Six cases of breast angiomatosis diagnosed at the Department of Pathology, the Seventh Medical Center, People's Liberation Army General Hospital and the Department of Pathology, Dongzhimen Hospital, Beijing University of Chinese Medicine from January 2011 to December 2023 were evaluated and reviewed. Results: All patients were female with an average age of 46 years at presentation, ranging from 25 to 62 years. The most common clinical presentation was a palpable unilateral breast mass with diameter ranging from 7 to 14 cm, and the average size was 11 cm. Histologically, all cases were composed of variably-sized ectatic, thin-walled blood vessels with minimal to no apparent smooth muscle, lined by flat normochromic endothelium without atypia, and diffusely infiltrating the breast stroma. Where present, the lesional vessels infiltrated between and around terminal duct lobular units but not into individual intralobular stroma. Immunohistochemical staining for CD31, CD34, Factor Ⅷ, Fli-1 and D2-40 revealed positive expression in vascular and/or lymphatic endothelial cells. Additionally, the Ki-67 proliferation index was found to be less than 1%. Conclusions: Angiomatosis of the breast is a rare benign vascular lesion. Distinguishing it from low-grade angiosarcoma requires careful consideration of the growth pattern, atypical features, and Ki-67 proliferation index.

Both primary and secondary care services in the NHS have been overwhelmed with an increase in referrals on the suspected cancer pathways. The years 2020/2021 saw 551,770 symptomatic breast referrals made in England alone. The Wessex Rapid investigations service in conjunction with the local district general hospital and primary care networks instigated a virtual triage for new breast symptoms. Over the course of a year, 664 people were assessed by either telephone or video using specially trained nurses. Appointments were given within 1-2 working days. The service was highly valued by patients and general practitioners. We were unable to confirm a reduction in referral to secondary care as the evaluation occurred during a postpandemic peak in referrals. We found that 10% of patients with new breast symptoms can safely self-manage. This percentage varied with the experience of the triage clinician. A specialist community face-to-face service could reduce further the need for full secondary care evaluation. Better integration and use of information technology systems would improve the service. The rapid responsiveness and length of consultations is valued by patients. Representation with the same symptoms was rare. This pathway utilises staff outside of the usual primary and secondary care providers and thus reduces the pressure on stretched systems.

Localized breast amyloidosis is often found incidentally on mammography or ultrasound, as amyloid deposits can be calcified and mimic malignancy. Although rare, breast amyloidosis should be considered a possible etiology of abnormal mammography findings in older women., (© 2024 Japan Geriatrics Society.)

Sclerosing lesions of the breast encompass a spectrum of benign and malignant entities and often pose a diagnostic challenge. Awareness of key morphologic features and pitfalls in the assessment of morphology and immunophenotype is essential to avoid over- or underdiagnosis and ensure optimal clinical management. This review summarizes nonneoplastic sclerosing lesions such as radial scar/complex sclerosing lesion, sclerosing adenosis, sclerosing intraductal papilloma, sclerosing variants of ductal adenoma and nipple adenoma, and fibroadenoma with extensive sclerosis, including their clinical presentation, characteristic morphology, differential diagnostic considerations, appropriate immunohistochemical work-up, when needed, and the clinical significance. In addition, atypical or neoplastic entities (such as atypical ductal hyperplasia, ductal carcinoma in situ, low-grade adenosquamous carcinoma, and fibromatosis-like metaplastic carcinoma) that can involve these sclerosing lesions are also briefly discussed., (© 2024 John Wiley & Sons Ltd.)

A female patient with a history of ductal carcinoma in situ in the left breast, status-post bilateral mastectomy with deep inferior epigastric perforator artery flap reconstructive surgery, presented with a right breast asymmetry concerning for fat necrosis. Histological analysis revealed the presence of benign glands and associated stroma within fibroadipose tissue, confirmed as endometriosis by immunohistochemical analysis. Further investigation revealed that the patient had a previous diagnosis of endometriosis associated with a cesarean section scar that likely seeded the ectopic endometrial glands into a tertiary site by utilizing abdominal tissue that may have harbored endometriosis., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

With the growing utilization and expanding role of breast MRI, breast imaging radiologists may encounter an increasing number of incidental findings beyond the breast and axilla. Breast MRI encompasses a large area of anatomic coverage extending from the lower neck to the upper abdomen. While most incidental findings on breast MRI are benign, identifying metastatic disease can have a substantial impact on staging, prognosis, and treatment. Breast imaging radiologists should be familiar with common sites, MRI features, and breast cancer subtypes associated with metastatic disease to assist in differentiating malignant from benign findings. Furthermore, detection of malignancies of nonbreast origin as well as nonmalignant, but clinically relevant, incidental findings can significantly impact clinical management and patient outcomes. Breast imaging radiologists should consistently follow a comprehensive search pattern and employ techniques to improve the detection of these important incidental findings., (© Society of Breast Imaging 2024.

Introduction: Breast tuberculosis (TB) is a rare extra-pulmonary presentation of tuberculosis. In the western world, this accounts for less than 0.1% of breast conditions (all breast conditions, not limited to TB or extra-pulmonary TB), but can be up to 3-4% in regions endemic for TB such as in Africa and Asia., Case Presentation: We report a case of a 54-year- old human immunodeficiency virus (HIV)-positive lady who presented with six months history of multiple masses on the left breast which were initially suspected to be cancer of the breast. However, histology report of the mass confirmed TB of the breast., Conclusions: Presentation of TB can be non-specific and atypical in patients with HIV infection, especially when it presents in extra-pulmonary forms., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2024 Iyonu J Onaghinor, Izuchukwu B Achusi, Olumuyiwa E Ariyo.)

Breast tuberculosis is a rare extrapulmonary manifestation of Mycobacterium tuberculosis , representing less than 0.1% of all breast pathologies in developed countries. However, in regions with high tuberculosis prevalence, such as India and Africa, its incidence is higher. The disease poses diagnostic challenges due to its ability to mimic breast carcinoma, leading to potential misdiagnosis and unnecessary surgical interventions. This study investigates the clinical and imaging characteristics of breast tuberculosis in a large cohort, with a specific focus on a rare case in a postmenopausal woman. A retrospective observational study was conducted on 1704 women who presented for mammography at the Alessandrescu-Rusescu National Institute for Mother and Child Health between 2019 and 2021. Clinical presentation, imaging results, and histopathological findings were analyzed to identify cases of breast tuberculosis. The study includes a comparative analysis with other granulomatous diseases and malignant breast conditions to highlight key diagnostic features. Among the 1704 patients, 714 (41.9%) presented with symptoms such as pain (35.4%), palpable lumps (13.2%), nipple discharge (4.3%), and breast appearance changes (2.1%). A rare case of primary breast tuberculosis was identified in a 69-year-old postmenopausal woman, presenting with a painless, palpable mass in the upper outer quadrant. Imaging demonstrated a hypoechoic mass with fine granular content and posterior acoustic enhancement, categorized as BIRADS 4A. The biopsy confirmed the diagnosis of breast tuberculosis. This study underscores the diagnostic complexity of breast tuberculosis, particularly in its ability to mimic malignancy. Through detailed imaging and clinical analysis, we emphasize the importance of biopsy in differentiating tuberculosis from breast cancer. Given the potential for misdiagnosis, clinicians should consider breast tuberculosis in differential diagnoses, especially in regions with high tuberculosis prevalence. Further research is needed to develop specific imaging criteria for earlier and more accurate diagnosis., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s).)

Breast microcalcifications are observed in 80% of mammograms, and a notable proportion can lead to invasive tumors. However, diagnosing microcalcifications is a highly complicated and error-prone process due to their diverse sizes, shapes, and subtle variations. In this study, we propose a radiomic signature that effectively differentiates between healthy tissue, benign microcalcifications, and malignant microcalcifications. Radiomic features were extracted from a proprietary dataset, composed of 380 healthy tissue, 136 benign, and 242 malignant microcalcifications ROIs. Subsequently, two distinct signatures were selected to differentiate between healthy tissue and microcalcifications (detection task) and between benign and malignant microcalcifications (classification task). Machine learning models, namely Support Vector Machine, Random Forest, and XGBoost, were employed as classifiers. The shared signature selected for both tasks was then used to train a multi-class model capable of simultaneously classifying healthy, benign, and malignant ROIs. A significant overlap was discovered between the detection and classification signatures. The performance of the models was highly promising, with XGBoost exhibiting an AUC-ROC of 0.830, 0.856, and 0.876 for healthy, benign, and malignant microcalcifications classification, respectively. The intrinsic interpretability of radiomic features, and the use of the Mean Score Decrease method for model introspection, enabled models' clinical validation. In fact, the most important features, namely GLCM Contrast, FO Minimum and FO Entropy, were compared and found important in other studies on breast cancer., (© 2024. The Author(s).)

Background: Mammography has become an invaluable tool for diagnosing breast lesions and detecting early breast cancer in women of 35 years and above., Aims: To correlate the mammography Breast Imaging Reporting and Data System (BI-RADS) categories with the histology in breast lesions and to determine the predictive values, sensitivity, specificity and accuracy of mammography., Patients and Method: This was a one- year prospective study carried out from March 2015 to February 2016. Consecutive female patients of 35 years and above with breast lesions at the University of Benin Teaching Hospital, Benin-City were recruited. Patients with fungating breast lesions and those who declined recruitment were excluded. All patients had mammography and core biopsy of the breast lesion which was examined histologically., Results: A total of 101 patients were studied. Five patients had bilateral breast lesions making a total of 106 biopsies that were performed. The mean age of patients with benign breast disease was 47.0 ± 4.9 years while those with malignant breast disease was 49.9 ± 8.5 years; P-value was 0.080 which was not statistically significant. Fibrocystic disease 6 (5.6%) was the most common benign disease while invasive ductal carcinoma was the most common malignant breast disease 84(79.2%). BI-RADS 5 correlated mostly with malignant breast disease (97.0%); P value < 0.001 and was statistically significant., Conclusion: This study showed that mammography is useful in the diagnosis of breast lesions in women who are 35 years and older. Patients with BI-RADS category 3, 4 and 5 had an increasing correlation with malignant breast disease., Competing Interests: The Authors declare that no competing interest exists, (Copyright © 2024 by West African Journal of Medicine.)

Diabetic mastopathy is a rare and benign pathology affecting young individuals with type 1 diabetes or autoimmune diseases. It clinically resembles breast cancer, necessitating a histological examination for a definitive diagnosis. These cases underscore the diagnostic challenges and the importance of histological examination. This report details two cases of diabetic mastopathy at Mohammed VI Hospital in Marrakech. The first case involved a 35-year-old with type 1 diabetes and mastodynia, revealing a 4 x 3 cm nodule in the left breast. Biopsies confirmed fibrous breast tissue with lymphocytic infiltrates, characteristic of diabetic mastopathy, with no recurrence during follow-up. The second case featured a 38-year-old with trisomy 21 and type 1 diabetes presenting with a right breast abscess. Drainage revealed lymphocytic infiltrates, confirming diabetic mastopathy. Though diagnostically challenging, diabetic mastopathy lacks a direct link to breast cancer. Long-term cancer risks in affected patients mirror the general population., Competing Interests: The authors declare no competing interests., (Copyright: Karam Harou et al.)

We aimed to construct and validate a multimodality MRI combined with ultrasound based on radiomics for the evaluation of benign and malignant breast diseases. The preoperative enhanced MRI and ultrasound images of 131 patients with breast diseases confirmed by pathology in Aerospace Center Hospital from January 2021 to August 2023 were retrospectively analyzed, including 73 benign diseases and 58 malignant diseases. Ultrasound and 3.0 T multiparameter MRI scans were performed in all patients. Then, all the data were divided into training set and validation set in a 7:3 ratio. Regions of interest were drawn layer by layer based on ultrasound and MR enhanced sequences to extract radiomics features. The optimal radiomic features were selected by the best feature screening method. Logistic Regression classifier was used to establish models according to the best features, including ultrasound model, MRI model, ultrasound combined with MRI model. The model efficacy was evaluated by the area under the curve (AUC) of the receiver operating characteristic, sensitivity, specificity, and accuracy. The F-test based on ANOVA was used to screen out 20 best ultrasonic features, 11 best MR Features, and 14 best features from the combined model. Among them, texture features accounted for the largest proportion, accounting for 79%.The ultrasound combined with MR Image fusion model based on logistic regression classifier had the best diagnostic performance. The AUC of the training group and the validation group were 0.92 and 091, the sensitivity was 0.80 and 0.67, the specificity was 0.90 and 0.94, and the accuracy was 0.84 and 0.79, respectively. It was better than the simple ultrasound model (AUC of validation set was 0.82) or the simple MR model (AUC of validation set was 0.85). Compared with the traditional ultrasound or magnetic resonance diagnosis of breast diseases, the multimodal model of MRI combined with ultrasound based on radiomics can more accurately predict the benign and malignant breast diseases, thus providing a better basis for clinical diagnosis and treatment., (© 2024.

Objectives: Studies show that anxiety and depression are widespread across patients presenting to outpatient services for medical illnesses. We expect similar or even higher prevalence in patients with breast complaints owing to the relevance of breasts in terms of sexuality, identity and confidence. Thus, this study was proposed to estimate the prevalence and identify risk factors for being at risk for anxiety and depression in patients seeking breast services., Design: Descriptive, cross-sectional study., Setting: Tertiary care teaching hospital in Mumbai, Western India., Participants: Patients seeking breast services for either benign or malignant conditions., Outcome Measures: Proportion of those at risk for clinical depression (defined as a score of ≥10 on Patient Health Questionnaire-9) and proportion of those at risk for clinical anxiety warranting further clinical evaluation (defined as a score of ≥10 on Generalized Anxiety Disorder-7) and their predictors., Results: A total of 208 patients were screened, and 192 consenting patients were enrolled. The prevalence of those at risk for anxiety requiring further clinical evaluation was 46.4% (95% CI 39.2% to 53.7%) and for those at risk for major depression that warrants further clinical evaluation by a mental health provider was 29.7% (95% CI 23.3% to 36.7%). The predictors of anxiety were age (adjusted odds ratio (aOR) 1.053; 95% CI 1.024 to 1.083; p<0.001) and postmenopausal status (aOR 2.475; 95% CI 1.200 to 5.103; p=0.014). The predictors of depression were age (aOR 0.954; 95% CI 1.927 to 0.981; p=0.001) and rural place of residence (aOR 2.362; 95% CI 1.023 to 5.433; p=0.044)., Conclusions: There is a high prevalence of being at risk for anxiety and depression among patients who seek breast services warranting further clinical evaluation. The predictors of being at risk for anxiety were higher age and postmenopausal status, and for those at risk for depression were young age and residing in rural areas., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Lymphocytic lobulitis (LL) is characterized by prominent lymphocytic infiltrates centered on lobules. Sclerosing lymphocytic lobulitis (SCLL) associated with diabetes mellitus (DM) or autoimmune disease (AI) was the first type to be described. Subsequently, non-sclerosing LL (NSCLL) was reported as an incidental finding in prophylactic mastectomies due to high risk germline mutations or a family history of breast cancer. The two types of LL were distinguished by stromal features and a predominant population of B-cells in the former and T-cells in the latter. In this study, 8 cases of NSCLL detected clinically or by screening were compared to 44 cases of SCLL. One case of NSCLL presented as a palpable mass, 2 as masses on screening, and 5 as MRI enhancement. In contrast, 80% of SCLL cases presented as palpable masses. Half the cases of NSCLL were associated with a BRCA1 or 2 mutation compared to 1 case of SCLL (2%). Three additional cases of NSCLL were associated with a strong family and/or personal history of breast cancer. Almost half (52%) of SCLL cases were associated with DM or AI, but only 25% of NSCLL. Immunoperoxidase studies confirmed a predominance of T-cells in NSCLL and B-cells in SCLL associated with DM or AI. It is important for pathologists to be aware of this new observation that NSCLL can be detected as a palpable mass or an imaging finding in diagnostic biopsies, as its presence can be indicative of a significant risk for breast cancer., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest.

Gigantomastia is a rare benign mastopathy of unknown aetiology. It usually occurs in women during puberty or during pregnancy. It is characterized by excessive breast growth, which is psychologically and physically disabling. It is a pathology little studied because of its rarity. In order to describe the epidemiological, clinical, diagnostic and therapeutic aspects, we report the case of four young women. The study was longitudinal over a period of 3 months. We collected data for 6 years from October 1, 2016, to October 31, 2021, at the surgery department B of the "Centre Hospitalier Universitaire du Point G". All patients who consulted for gigantomastia were included. At the end of our study, we found three cases of juvenile gigantomastia and one case of prepubertal gigantomastia. The couple mammography ultrasound performed in two patients, adenofibroma was associated with breast hypertrophy in one patient. The treatment was essentially surgical in our study. Reduction mammoplasty according to the technique of Mc Kissock and modified Mc Kissock was used. We did not note any complication such as nipple-areolar necrosis. All our patients were satisfied with the result., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Abstract: Tuberculosis (TB) remains a significant global health concern and kills millions of people every year. While TB can affect any organ in the body, breast TB is relatively uncommon. This study presents a comprehensive review of literature spanning 23 years, with a focus on cases of breast TB in Iran. Among the 96 cases found, the majority (89.6%) fell within the age range of 20-60, with a striking prevalence among women (98.9%). Common symptoms included pain and palpable mass, each presenting in approximately 60.4% of cases. Notably, only a quarter of patients had a confirmed history of exposure to a known TB case. Left breast involvement was more prevalent (58.3%), with ipsilateral lymph node enlargement observed in 40.6% of cases. Given the clinical presentation of breast TB, which often leads to misdiagnosis, a significant proportion of cases (68.7%) were diagnosed through excisional biopsy. Following a standard 6-month regimen of anti-TB drugs, relapse occurred in only 4.2% of cases. This study highlights the need for heightened awareness and vigilance in diagnosing breast TB, especially in regions with a high burden. Although breast TB poses diagnostic challenges, with prompt identification and treatment, the prognosis is generally favorable, with a low incidence of relapse., (Copyright © 2024 Copyright: © 2024 International Journal of Mycobacteriology.)

Background: Nipple-areolar complex (NAC) conditions affect reproductive-age women, yet it is not known how care of NAC complaints is distributed among medical specialties. There is a need to characterize all NAC conditions, including their treatment and the care team involved in their clinical management, of nonlactating and lactating patients to determine care gaps. Materials and Methods: This was a retrospective cohort study of reproductive-age females who presented to a large tertiary health system with an NAC complaint between 2015 and 2020. Data about the symptoms, diagnosis, specialty providing care, diagnostic considerations, and treatments were collected. Results: Nipple pain, dermatitis, and thrush were the most common diagnoses among 407 encounters (215 patients). Lactating patients represented half (204, 50%) of the study sample. Benign breast conditions like obstructed ductal openings, accessory nipples, nipple growth, inverted nipples, and chronic and bacterial infections represented a third of all encounters. Primary care physicians (167, 41%) and obstetricians (105, 26%) provided most of the care and referred a third and quarter of patients, respectively, to another provider. Conclusion: The care of patients with NAC complaints is not limited to obstetricians. Internal medicine, family medicine, emergency medicine, and obstetrician-gynecology, dermatology, and surgery resident physicians should receive training in benign breast conditions and clinical lactation.

Objective: To assess the impact of informing women about the presence of breast arterial calcification (BAC) on mammography by determining whether those notified about the presence of BAC would seek cardiovascular evaluation., Methods: This IRB-approved prospective study included 494 patients who underwent screening mammography between June 8, 2021, and April 22, 2022. Mammograms were reviewed by a radiologist, and patients were notified via e-mail about the presence or absence of BAC. Patients with BAC were advised to discuss the results with their physicians and were surveyed 3 months later. Frequencies and proportions were calculated for study participation, presence of BAC, survey participation, health actions, and perceptions. Confidence intervals were calculated for proportions of health actions and perceptions., Results: Of 494 study participants, 68/494 (13.8%; 95% CI: 10.9%-17.1%) had BAC detected on mammography and 42/68 (61.8%; 95% CI: 61.1%-62.1%) with BAC completed the follow-up survey at 3 months. Of these 42 survey respondents, 24/42 (57.1%; 95% CI: 41.1%-72.3%) reported discussing results with their primary care physician (PCP) or a cardiologist. In addition, 34/42 (81.0%; 95% CI: 65.9%-91.4%) reported finding it helpful to receive information about BAC and 32/42 (76.2%; 95% CI: 60.6%-88.0%) believed all women should be informed about BAC after mammography., Conclusion: After notification about the presence of BAC on screening mammography, the majority (57.1%) of survey respondents reported discussing the results with a PCP or cardiologist. These results suggest that providing mammography patients with information about BAC may promote preventive cardiovascular health., (© Society of Breast Imaging 2023. All rights reserved.

Breast tumor diseases include a wide range of pathologies that require different approaches to their treatment. MicroRNA (miR) levels, reflecting regulation of the gene expression involved in tumorigenesis, can be diagnostic and prognostic markers of breast diseases. The levels of circulating miR-181a and miR-25 were measured in patients with benign breast diseases (BBD), patients with invasive carcinoma of a nonspecific type (ICNT) and also in conditionally healthy women. Expression of both miRs was higher in patients of both groups as compared to controls; at the same time, the content of serum miR-181a and miR-25 was higher in BBD patients than in ICNT patients. The detected changes may be of interest in the context of precancerous changes in BBD. It seems possible to use them in the future as markers of the pathological process as a part of a large diagnostic panel.

Abstract: Pseudoangiomatous stromal hyperplasia (PASH) is a benign entity of the breast and typically found incidentally or as a palpable mass. It usually affects women in the reproductive age group. In men, it is associated with gynecomastia. While the exact etiology is unknown, PASH is considered hormonally responsive. The mammography and ultrasonography findings are nonspecific. Grossly, PASH is a well-circumscribed, firm, rubbery mass with solid, homogenous, gray-white cut surface. On histologic examination, it is characterized by the presence of open slit-like spaces in dense collagenous stroma. The spindle cells express progesterone receptors and are positive for vimentin, actin, and CD34. PASH lesions should be surgically excised if increasing in size or associated with symptoms, also in cases of suspicious imaging findings or other lesions are synchronously diagnosed that require excision. In other small incidentally detected asymptomatic cases observation with clinicoradiological follow-up can be considered. It is associated with a good prognosis with no increased risk to develop breast cancer. Hence, the operating surgeon and pathologist should be aware of this not so uncommon entity so that patients are not subjected to unnecessary excision and subsequent physical and mental morbidity associated with it. In this article, we present a case report and also provide a brief review of the sparse literature on PASH, discussing clinical presentation, etiology and pathogenesis, radiopathological features, differential diagnosis, and the implications for further patient management and prognosis., (Copyright © 2023 Copyright: © 2023 Journal of Cancer Research and Therapeutics.)

Purpose: Screening programs use mammography as a diagnostic tool for the early detection of breast cancer. Mammogram enhancement is used to increase the local contrast of the mammogram so that the lesions are more visible in the advanced image. For accurate diagnosis in the early stage of breast cancer, the appearance of masses and microcalcification on the mammographic image are two important indicators. The objective of this study was to evaluate the feasibility of the automatic separation of images of breast tissue microcalcifications and also to evaluate its accuracy., Methods: The research was carried out by using two techniques of image enhancement and highlighting of breast tissue microcalcifications for the desired areas by regional ROI based on fuzzy system and also Gabor filtering method. After determining the clusters of breast tissue microcalcifications, the clusters are classified using the decision tree classification algorithm. Then, for segmentation, samples suspected of microcalcification are highlighted and masked, and in the last stage, tissue characteristics are extracted. Subsequently, with the help of an artificial neural network (ANN), determining the benign and malignant types of segmented ROI clusters was accomplished. The proposed system is trained with a Digital Database for Screening Mammography (DDSM) developed by the University of South Florida, USA, and the simulations are performed under MATLAB software and the results are compared with previous work., Results: The results of this training performed under this work show an accuracy of 93% and an improvement of sensitivity above 95%., Conclusion: The result indicates that the proposed approach can be applied to ensure breast cancer diagnosis., (© 2023.

Breast masses are infrequently encountered in pediatric and adolescent populations. Most breast masses in children are benign entities arising from embryological defects which can be managed once breast development is complete. Diagnostic and management dilemmas arise when fibroepithelial lesions of the breast are seen in clinical practice. Differentiation between a fibroadenoma and a phyllodes tumor is important to guide management. Breast cancer in children under 18 years of age is extremely rare and invasive diagnostic testing and aggressive management is only recommended when clinical suspicion of malignancy is very high. Patient and caregiver counseling plays an important role in the management of these diseases. While adult-onset breast diseases have been studied very closely, there is a dearth of literature on pediatric breast anomalies. This review aims to provide a scoping overview of the available literature on benign, fibroepithelial, and malignant lesions of the breast in pediatric and adolescent populations to help guide physicians and surgeons with decision-making regarding the diagnosis and management of pediatric breast diseases., Competing Interests: Declaration of Competing Interest The authors have no conflicts or fundings to disclose., (Copyright © 2023 Elsevier Inc.

Background: Classically, urgent breast consults are seen by Breast Surgery or Surgical Oncology (BS/SO). At our safety net hospital, Acute Care Surgery (ACS) performs all urgent surgical consultations, including initial assessment of breast consults with coordinated BS/SO follow-up. The objective was to determine safety of ACS initial assessment of acute breast pathology., Methods: All urgent breast-related consultations were included (2016-2019). Demographics, consult indications, and investigations/interventions were captured. Outcomes were compared between patients assessed by ACS versus both ACS and BS/SO at presentation., Results: 234 patients met study criteria, with median age 39 years. Patients were primarily Hispanic (82%) women (96%). Most were not seen by BS/SO at presentation (69%), although BS/SO assessment was more frequent among patients ultimately diagnosed with cancer (8% vs 1%, P = .012). No patient had delay >90 days to core biopsy from presentation. Outcomes including time to cancer diagnosis (14 vs 8 days, P = .143) and outpatient BS/SO assessment (16 vs 13 days, P = .528); loss to follow-up (25% vs 21%, P = .414); and ED recidivism (24% vs 18%, P = .274) were comparable between patients seen by ACS versus ACS/BS/SO at index presentation., Conclusion: Urgent breast consults at our safety net hospital typically underwent initial assessment by ACS with outpatient evaluation by BS/SO. Time to follow-up and cancer diagnosis, loss to follow-up, and ED recidivism were similar after index presentation assessment by ACS versus ACS and BS/SO. In a resource-limited environment, urgent breast consults can be safely managed in the acute setting by ACS with coordinated outpatient BS/SO follow-up.

1. An experiment was carried out to validate techniques as predictive diagnostic tools for breast myopathies and to study the allometric growth of distinct parts of the body and meat quality of broilers.2. Infrared thermography was performed at 35 d of age. The surface temperatures of breasts of 300 birds were recorded, followed by ultrasound imaging.3. The birds were slaughtered and the cuts were made to weigh the body parts. Then, the breasts were evaluated as for the presence and severity of myopathies, from which nine treatments were established represented by the associated degrees of the myopathies white striping and wooden breast and breasts classified as normal.4. There was no difference in surface temperatures and echogenicity values between normal breasts and breasts affected by myopathies. At 35 d of age few fillets classified as normal were found.5. The breast showed late growth in relation to the body, regardless of characteristic lesions of myopathies. The most severe score of wooden breast affected meat quality variables.

Background: Distinguishing benign breast diseases (BBDs) from malignant breast diseases is a worrisome entity and should also have knowledge of the pattern of occurrence of the disorders in their geographical location. This research aimed to study the clinical and histopathological pattern of BBD in Indian patients., Materials and Methods: The study was conducted on 153 specimens from lumpectomy, core needle biopsy, and mastectomy. Data regarding patients' age, sex, presenting complaints, duration of the complaints, and history of menstrual cycles and lactation were collected from the biopsy requisition forms and case papers. The tissue bits were processed and stained with hematoxylin and eosin, and a histopathological examination was performed., Results: Most of the patients in the present study were females (n = 151, 98.7%). The mean age of the patients was 30.45 years. Most of the BBD cases (n = 118, 77.14%) were benign, of which fibroadenoma (101 cases) accounted for 66%. Majority of the lesions were in the upper outer quadrant (39.22%). Of the 153 cases, 94 cases of fibroadenoma, one case of breast abscess, nine cases of fibrocystic change, four cases of phyllodes, three cases of lipoma, and one case of gynecomastia diagnosed clinically correlated well with histopathology (n = 112, 73%)., Conclusion: BBDs are mostly seen in female patients in the age group of 21-30 years. Fibroadenoma is the most common BBD. Clinical assessment followed by histopathological examination provided an accurate diagnosis. The clinical diagnosis correlated well with histopathology., Competing Interests: None

Microcalcifications play an important role in cancer detection. They are evaluated by their radiological and histological characteristics but it is challenging to find a link between their morphology, their composition and the nature of a specific type of breast lesion. Whilst there are some mammographic features that are either typically benign or typically malignant often the appearances are indeterminate. Here, we explore a large range of vibrational spectroscopic and multiphoton imaging techniques in order to gain more information about the composition of the microcalcifications. For the first time, we validated the presence of carbonate ions in the microcalcifications by O-PTIR and Raman spectroscopy at the same time, the same location and the same high resolution (0.5 μm). Furthermore, the use of multiphoton imaging allowed us to create stimulated Raman histology (SRH) images which mimic histological images with all chemical information. In conclusion, we established a protocol for efficiently analysing the microcalcifications by iteratively refining the area of interest.

B3 lesions of the breast are a heterogeneous group of lesions with uncertain malignant potential encompassing a broad spectrum of histologically distinct alterations that often pose challenging decisions if diagnosed on the preoperative core or vacuum biopsies. B3 lesions are mostly detected due to mammographic calcifications or mass lesions and, in most cases, encompass a spectrum of atypical lesions such as atypical ductal hyperplasia, classic lobular neoplasia, flat epithelial atypia, papillomas, fibroepithelial tumors, and rarely other lesions such as mucocele-like lesions, atypical apocrine lesions, and rare stromal proliferations. The use of immunohistochemical stains (estrogen receptors, basal cytokeratin, myoepithelial markers, and stromal marker panel) is useful in the differentiation of these lesions and allowing proper classification. Regarding clinical management of B3 lesions, the radiological-pathological correlation of the given entity plays the most important key element for the proper next diagnostic and therapeutic step., (© 2023.

Breast conditions in pediatric and adolescent patients vary from benign congenital changes to pathological findings. Although most breast conditions are benign, there are rare cases of malignancy that are important to identify during development. As such, it is critical to understand the classification and management of the different pediatric and adolescent breast conditions that might present to clinicians who care for pediatric and adolescent patients. In this review, congenital, benign, and malignant pediatric/adolescent breast conditions are discussed., Competing Interests: Conflict of Interest Statement None., (Copyright © 2022.

Background: Pseudoangiomatous stromal hyperplasia is a rare benign breast stromal proliferative lesion of the breast. Clinical presentation ranges from rapidly growing mass to incidental identification in routine screening. This difference in manifestation and its rarity makes it difficult to be a standard treatment protocol. Therefore, we aimed to share our clinical experience in Pseudoangiomatous stromal hyperplasia., Methods: The files of patients who underwent core biopsy or surgical excision due to a breast mass and resulted in pseudoangiomatous stromal hyperplasia between January 2013 and December 2021 were included in the study., Results: 17 patients with a median age of 37 (22-68) were found Pseudoangiomatous stromal hyperplasia confirmed by surgical excision or core biopsy. Chosen treatment option was observation in 8 patients (47.1%), while surgical excision was used in 9 (52.9%) patients. The mean follow-up period was 55.24 ± 26.72 (13-102) months. None of the patients observed the Malignant transformation during the follow-up period., Conclusion: For Pseudoangiomatous Stromal Hyperplasia of the breast, surgical excision with clean margins or close follow-up after diagnosis confirmation by tissue biopsy is sufficient. Pseudoangiomatous Stromal Hyperplasia is not a risk factor for developing breast cancer.

Cholesterol granuloma of the breast is an infrequent benign lesion with clinical and radiological findings suggestive of cancer. Herein, we present the case of a 52-year-old woman with no significant past medical history, who presented to the outpatient department for her routine breast screening. Physical examination revealed a painless palpable nodule in the upper external quadrant of the left breast, measuring 0.7 cm. On imaging, the mass met the criteria for Breast Imaging Reporting and Data System (BI-RADS) category 4B. Subsequently, a core needle biopsy of the mass was performed. Despite the alarming radiologic features, microscopic findings were consistent with breast cholesterol granuloma.
