Aims: Spleen masses, which are discovered on imaging studies, usually create difficulty in diagnosis and treatment. Except for lymphomas involving the spleen, primary and secondary neoplasms are rare and discovered by chance. This study analyses a series of splenectomies in a surgical clinic to evaluate the management of incidentally diagnosed splenic masses. Study Design: This retrospective study included patients operated for spleen masses between 2010 and 2021. Patients with a history of lymphoproliferative disease and splenectomy performed as part of a larger resection were excluded. Methodology: The patients were divided into three groups, i.e. cystic, benign and malignant, based on the results of pathological examinations. The groups were compared in terms of age, gender, tumor size, and previous history of malignancy. Results: Splenectomy was performed in 512 patients in 11 years, 62 of whom had solid and cystic lesions detected on imaging. Thirty-five patients (56,5%) were female and the median age was 40 years (range: 18-80 years). Forty-four patients (71%) had distinct symptoms. Radiological evaluations of all the patients were made. Diagnostic biopsy could not be performed in any of the patients. The final pathological examination showed cysts in 38 patients (61,3%), benign lesions in nine patients (14,5%) and malignant lesions in 15 patients (24,2%). Out of 15 patients with malignant lesions, one patient had Hodgkin’s lymphoma, four patients had diffuse large B cell lymphoma and ten patients had metastatic tumors. There was a significant difference in age between the groups and the malignant group was older (p = 0.017). The size of the lesions also significantly differed and the malignant lesions had a significantly smaller diameter (p = 0.014). A significantly higher rate of the malignant group had a previous history of cancer (p˂0,001). Conclusion: Spleen neoplasms are masses that are difficult to diagnose. Most of them are asymptomatic and are found after splenectomies by coincidence. Splenectomy can be utilized as both a diagnostic and curative method. It should be kept in mind that the lesions detected in the spleen in patients with a history of malignancy can be metastatic.

OBJECTIVE To evaluate breast cancer patients with low F18-fluorodeoxy-glucose positron emission tomography/computed tomography scan (FPET) of axilla standardised maximum uptake value (SUVmax) along with their histopathological findings regarding axillary lymph node metastasis (LNM). STUDY DESIGN A descriptive study. Place and Duration of the Study: Adana City Education and Research Hospital, Turkey, from January 2015 to October 2018. METHODOLOGY The current study analysed the findings of 113 patients according to age, histopathological axillary LNM, estrogen and progesterone receptor status, tumour size, histological grade, Ki-67, HER2 and preoperative FPET SUVmax findings. Histopathological and immunohistochemical comparisons were made between FPET axilla SUVmax and univariate and multivariate parameters in breast carcinoma in terms of LNM. RESULTS The authors analysed the receiver operator characteristic curve for the FPET axilla SUVmax and set the cut-off value to 1.84 to predict LNM. However, it was also found that the SUVmax detected metastases in the axilla at values lower than 1.84. In the multivariate analysis, a statistically significant relationship was found between axilla LNM cases that have FPET axilla SUVmax less than 1.84, a Ki-67 index greater than 15% and tumour size greater than 2 cm (p

Objective This study aimed to examine the rare locally aggressive intermediate tumors and malignant primary breast mesenchymal tumors in patients receiving surgical treatment. Summary of background data Locally aggressive intermediate tumors were subdivided into nonmetastasizing and rarely metastasizing, and the malignant group was subdivided as a single subgroup called able to metastasize. A retrospective examination of surgical notes and clinical charts was carried out reviewing gender, age, symptoms, duration of symptoms, tumor size, clinical presentation, radiation history, kind of surgery undergone, adjuvant radiotherapy, adjuvant chemotherapy, local recurrences, systemic metastases, and mortality. Results Mitotic index and Ki-67 were statistically different between locally aggressive and malignant groups (P < 0.001). One local recurrence occurred in only 1 patient diagnosed as dermatofibrosarcoma protuberans among all patients. None of the entities showed distant metastasis or mortality. In this result, clear margin of surgery in locally aggressive intermediate group and combination of surgery with radiation therapy in the malignant group was the most important determinant for the prospect of the patients with mean follow-up of 28 months. Conclusion The main treatment for localized mesenchymal breast tumors is surgery. When the disease is locally advanced or malignant with high mitotic index, radiotherapy with surgery is predominantly used. Targeted therapies are promising with the limited place of chemotherapy.

Background and Aims The complete pathological response (pCR) following neoadjuvant chemotherapy (NAC) in breast cancer is essential for the accurate prediction of prognosis. We aimed to evaluate the efficacy of the presence and type of peritumoral edema detected by magnetic resonance imaging (MRI) in predicting pCR to NAC in breast cancer patients. Methods and Results One hundred five patients with the diagnosis of invasive carcinoma were evaluated by MRI before NAC. Edema was evaluated in fat-suppressed T2-weighted images. The patients were categorized into three groups: patients with no peritumoral edema, patients with peritumoral edema, and patients demonstrating subcutaneous edema. The cases were categorized as being pCR and non-pCR. Molecular subtypes, lymphovascular invasion (LVI), tumor size, and apparent diffusion coefficient (ADC) were evaluated. A positive relationship was found between the presence of edema and tumor size. Subcutaneous edema was found to be statistically higher in non-pCR patients. While the number of pCR patients with subcutaneous edema was 17 (30.4%), the number of non-pCR patients with subcutaneous edema was 26 (53.1%) ( p = 0.018). LVI was found to be statistically higher in patients with edema. The number of edema-negative and LVI (+) patients was 4 (15.4%), while the number of edema-positive and LVI (+) patients was 28 (35.4%) ( p = 0.042). Intratumoral and peritumoral ADC values were significantly higher in tumors with edema. Conclusion The presence of subcutaneous edema and LVI may be utilized for the prediction of pCR outcomes in breast cancer patients scheduled for NAC treatment.

The most common cause of neurological symptoms in patients with systemic malignant tumors is central nervous system (CNS) metastases, and CNS metastases are one of the important causes of morbidity and mortality in these patients. The most common metastatic tumors to the CNS are lung, breast, malignant melanoma, genitourinary, and gastrointestinal tumors. We aimed to analyze our data on patients with CNS metastases in our department, which belongs to a large archive in the field of neuropathology. The data of patients who had CNS metastases between January 2015 and August 2021 in our department were reviewed retrospectively. The patients were grouped in terms of demographic data, location, histopathological diagnosis, and primary origin characteristics, and their frequency and immunohistochemical staining characteristics were investigated.There were 256 patients with CNS metastases in our study. The mean age was found to be 56.12. Of the patients, 30.5% were female and 69.5% were male. Astrocytic and oligodendral tumors (25.3%), followed by meningiomas (24.1%), and then CNS metastases (21.3%) were the most common CNS tumors. Among the CNS metastases, the most common primary sites were the lung (58%), breast (16%), tumors of unknown primary origin (TUP) (5%), colon (4%), and gynecologic tract (3.1%). Localization was found as cerebral (69.5%), cerebellar (28.1%), and spinal (2.3%).In CNS system metastases, an accurate histological diagnosis should be made by histomorphological evaluation supported by compatible immunohistochemical results in the presence of clinical history and radiological findings. Despite performing a larger immunohistochemical panel, it should be kept in mind that a primary site of origin cannot be found in a significant number of cases.

To determine the effectiveness of Milan system for the evaluation of aspiration cytology to salivary gland lesions classification.Cross-sectional observational study.Department of Pathology, Tertier Centre, University of Health Sciences, Adana City Education and Research Hospital, Adana, Turkey from January 2014 to December 2020.Salivary gland aspiration cytology of the last six years was recategorised, according to Milan classification. Risk of malignancy (ROM) and risk of neoplasm (RON) were determined among the subgroups in the cytological materials of 233 patients, who had undergone excisional biopsy.Forty hundred and eighty salivary gland aspiration cytologies were available, in which 250 (52.1%) cases were males and 230 (47.1%) were females. The mean age was 52.36 ± 16.05 years. When aspiration cytology of 233 patients with resection were evaluated, according to Milan classification, ROM in non-diagnostic category was 9.5%, ROM in non-neoplastic category was 19.2%, and ROM in neoplasm-benign category was 8.2%. ROM were found 100% in the suspected malignancy and malignancy categories. There were no patients in the atypia category of undeterminate significance.In aspiration cytology of salivary gland lesions, Milan system provides useful information in classifying patients for clinical follow-up and treatment. However, it can be said that it is difficult to distinguish between the atypia of uncertain significance and neoplasm categories. Key Words: Salivary glands, Biopsy, Fine-needle, Milan classification.

This study was to investigate the effect of mesorectal fat tissue volume (MRV) on the pathological response to neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced rectal cancer.88 patients who had been diagnosed with locally advanced rectal cancer between January 2017 and June 2020 were reviewed retrospectively. The total abdominal, subcutaneous, visceral, and mesorectal fatty tissue components were measured semiquantitatively by two radiologists using computed tomography (CT)-based findings. The patients were divided into two groups as those with and without a pathological response to nCRT. The relationship of MRV with the other fat tissue components of the body was also evaluated.We performed a retrospective analysis of 88 patients (mean age 62.7 years [range, 33-90 years]; 31 males and 57 females). A positive response to nCRT was present in 47 patients. There were 59 patients with stage 3 disease. 46 patients demonstrated lymph node involvement. The mean MRV was 69.6 ± 31.0 ml in no-response group and 105.8 ± 47.5 ml in response-positive patients (p 0.05). MRV showed the highest correlation with visceral fat volume (VFV). There was a negative correlation between the MRV and the N stage. A cut-off value of ≥ 69.4 for MRV predicted the repsonse to nCRT, with 82.9% sensitivity and 58.5% specificity [AUC: 0.757 (0.653-0.842), p 0.001] in receiver operating characteristic (ROC) curve analysis CONCLUSIONS: MRV can be used as a novel parameter in predicting of pathological response to nCRT in locally advanced rectal cancer patients.

Background: In our study, thyroid fine-needle aspiration biopsy (FNAB) data in the same calendar period of 1 year before and after the COVID-19 pandemic were compared.Methods: Thyroid FNAB data for the same calendar period of 1 year before and after the COVID-19 pandemic were included in the study. The patients were grouped according to age, gender and thyroid FNABs according to the Bethesda system for reporting thyroid cytopathology, and the data of both groups were compared considering the diagnoses of the patients who underwent thyroid surgery afterwards.Results: In the post-pandemic period, the number of thyroid FNABs and the number of patients over the age of 40 decreased (all p

Aim: Studies on childhood soft tissue tumors have generally been conducted with malignant tumors. There are few studies in the literature comprising all soft tissue tumors. The current study aimed to examine the incidence of all benign and malignant soft tissue tumors during childhood in East Mediterranean region.Materials and Methods: This study retrospectively analyzed the data gathered from patients diagnosed with soft tissue tumors according to the WHO 2020 classification. It focused on those aged 0–18 years that underwent excisional biopsy at Adana City Training and Research Hospital (Adana, Turkey) between 2014 and 2020.Results: Of the total patients, 47.5% were female and 52.5% male. Of these, 87.2% of the cases were benign, 9.2% malignant, and 3.6% intermediate. Hemangioma (55%) was the most common benign soft tissue tumor, and the most common location was the head–neck. Other benign soft tissue tumors were neurofibroma (8.8%), lipoma (6.1%), schwannoma (5.1%), and neuroma (4.4%). Rhabdomyosarcoma (53.2%) was the most common malignant soft tissue tumor. The embryonal subtype was the most common (36.6%). Other malignant soft tissue tumors were extra-osseous PNET/Ewing’s sarcoma (16.6%), synovial sarcoma (13.3%), and leiomyosarcoma (3.3%).Conclusion: Similar to the literature, in this study, the most common benign soft tissue tumor in children was hemangioma, and the most common malignant soft tissue tumor was rhabdomyosarcoma. It is hoped that this study will contribute to the literature as it is the first study to cover all childhood soft tissue tumors at national and regional scale.

Objectives: The object of the study is to experimentally investigate the possible systemic side effects of Oxymetazoline including its nasal spray which has been in use for a long time both by the physicians and patients. There is no study in the literature to address the damages of oxymetazoline on the end organ. Materials and methods: The study conducted on 2 groups of rat. Group 1 (n = 8): Control; and Group 2 (n = 8): Oxymetazoline. During 4 week, the control group was applied with 2 drops of saline water on each nasal cavity 3 times a day and the other group was applied with 2 drops of oxymetazoline HCl 3 times a day. At the end of experiment, samples from mandible, parotid and tails of the rats were taken in 10% formalin for histopathological investigations. Results: In histopathological experiments, when compared with the control group, the oxymetazoline group showed significant increase in many of the histopathological parameters (ischemic changes: P = 0.0001; congestion: P = 0.0006; arterial thrombosis: P = Ns; PNL accumulations: P = 0.001; necrosis: P = 0.0001; and ulceration: P = 0.014). The results of histopathologic tests on the samples taken from mandible and parotid gland, in comparison with the control group, showed no significant increase (focal inflammation: P = Ns; and lymphocyte aggregation: P = Ns). Conclusion: Due to the damage that the long-term use of nasal spray including oxymetazoline, it may cause injury on the end organ, which we revealed in our histopathological experiments. We believe that it’s essential for the physicians to provide information on the side effects of the medicine to their patients who use for a long term.
