Introduction There are multiple management modalities for idiopathic granulomatous mastitis, but the treatment of choice is still under debate. This study aims to evaluate the diagnosis and outcomes of different management modalities in patients with idiopathic granulomatous mastitis and to identify the risk factors associated with recurrence. Method This is a single-group cohort study that included those patients who had idiopathic granulomatous mastitis. Ultrasonography was conducted for all of the cases using LOGIQ E9 with an ML6-15 transducer (5-15 MHz). A core needle biopsy was conducted to take samples from the cases for histopathological examination. The patients were put on steroid therapy. Whenever the cases did not respond to the steroid therapy, treatment with a combination of low-dose steroids and methotrexate was started. In the lack of response to conservative treatments, surgical interventions were started. Results Sixty-three cases with a confirmed histopathological diagnosis of granulomatous mastitis were included. The mean age of patients was 35.7 years. The history of more than one childbirth was positive in a large portion of the cases (82.5%). The lesion side was unilateral in 58.7% of the cases. A large proportion of the lesions were classified as BI-RADS category 2. The best treatment outcome was yielded by a combination of low-dose steroids and incision and drainage. The factors of age, lesion area (cm2), skin thickening, and white blood cell count enhanced the chance of recurrence. Conclusion Incision and drainage in combination with a low dose of steroids can give an acceptable outcome with a low rate of recurrence.

Introduction Accessory breast (AB) is extra and ectopic breast tissue. Fibroadenoma (FA) in AB is a rare finding. This study aims to present a case of FA in axillary AB mimicking carcinoma of unknown primary (CUP). Case report A 38-year-old female presented with a mass in her right axilla. She had a mass in her right breast for 5 years. She previously had a left breast lumpectomy for a benign condition. The lump in her axilla was palpable and hard. Ultrasound showed an oval lymph node in the level I axilla (12*6mm) with blurred and unclear fatty hilum, suspicious for malignancy. Magnetic resonance imaging revealed an oval lesion (12*7mm) in the level I axilla with no fatty hilum and with heterogeneous enhancements, suggesting abnormal nodes. Fine needle aspiration of the axillary mass suspected CUP. But core biopsy resembled FA. Both masses in the right axilla and breast were surgically excised. Histopathology confirmed FA in both masses. Discussion Although pathologies in AB are uncommon, it is still susceptible to the same malignant and benign transformations that are found in normal breasts. The axilla is the most frequent location for FA in AB and often affects young women. Imaging techniques can be inconclusive and only histopathology can conclude a definitive diagnosis. Conclusion FA in axillary AB is a rare condition that causes a diagnostic dilemma as it can be mistaken for other benign or malignant pathologies., Highlights • Accessory breast is having extra and ectopic breast tissue. • Fibroadenoma in the accessory breast is a very rare finding. • It can be mistaken for other malignant pathologies. • This report presents a case of fibroadenoma in axillary accessory breast mimicking carcinoma of unknown primary.

Introduction Desmoid tumor is an uncommon tumor with variable spectrum ranged from being a locally lesion to an aggressive and destructive one. The current case aims to report a rare condition of desmoid type fibromatosis of the breast. Presentation of case A 59-year-old female presented with a right breast mass for 9-months. Mammography showed a small speculated iso-hyper dense mass, just anterior to the pectoralis muscle measuring about 15 mm (M5) in longest axis. Ultrasound examination revealed an irregular mass with internal vascularity and posterior shadowing in the right breast with a single borderline lymph node (25 ∗ 14 mm of 4 mm cortex). Wide local excision with sentinel axillary lymph nodes biopsy was performed. Histopathological examination of the specimen confirmed the diagnosis of desmoid type fibromatosis of the breast. Discussion The etiology of this tumor is unknown, however, physical, hormonal and genetic factors have a significant role in the development of desmoid tumor. Conclusion Desmid type fibromatosis of the breast is an uncommon, benign, locally aggressive fibroblastic tumor with lack of metastatic potential, it may present with features of malignancy., Highlights • Desmoid tumor is an uncommon tumor. • The occurrence of desmoid tumor in the breast is even rarer. • Differentiation from malignant disease is a challenging task. • The current report discusses a case of desmoid type fibromatosis of the breast.

Introduction Lymphedema affects the extremities of breast cancer patients post-surgical or radiation therapy. This study aims to report a case of primary lymphedema of breast. Case presentation A 41-year-old female presented with right breast swelling. It associated with hotness and intermittent mastalgia for the past 8 years. Ultrasound (US) examination showed diffuse trabeculate, skin thickening and edematous with normal glandular tissue. Magnetic resonance imaging (MRI) showed diffuse homogeneous parenchymal enhancements with diffuse tranecular and skin edema (high signal on Short-TI Inversion Recovery (STIR)). The result of the biopsy showed normal breast tissue and lymph node. Discussion The major risk factors of lymphedema are breast cancer surgery, radiation therapy, axillary lymph node dissection, length and location of breast incision, taking biopsy, trauma, wound infection. Forearm is the most common site of swelling. Primary lymphedema of the breast is a very rare condition without a known risk factor. Conclusion Although it is rare, primary lymphedema can affect the breast. US and MRI are necessary to exclude other pathologies. It is managed conservatively., Highlights • Lymphedema mainly develops in breast cancer patients post-operatively. • Usually affects the extremities and rarely occur in the breast • It is characterized by the accumulation of extracellular fluid. • In this paper, a case of breast lymphedema has been discussed.

Introduction Cancer of the breast is the most common cancer among females. The current study aims to report and discuss a rare case of breast cancer in the intermammary region. Case report A 61-year-old lady presented with intermammary swelling for three months. Ultrasound examination showed a hypoechoic micro lobulated mass with internal vascularity seated on the chest wall. There was pathological lymphnodes in the right axilla. Core needle biopsy suspected invasive ductal carcinoma of no specific type. The patient was referred to an oncology center receiving 21 cycles of radiotherapy and hormonal therapy. Discussion The most common site of the occurrence of breast cancer is the upper outer quadrant (found in one-third of patients), followed by the upper inner quadrant (9.4%)—both lower outer and inner quadrants (5.2%) and rarely in the central portion. Intermammary breast cancer is an infrequent finding. Conclusion Although it is extremely rare, breast cancer could occur in the intermammary region. It has the same management strategy as breast cancer., Highlights • Cancer of the breast is the most common cancer. • It is still a major problem of the public health. • Intermammary breast cancer is a sporadic condition. • In this study a rare case of intermammary breast cancer is reported.
