    Neuroendocrine Tumors of the Breast: Single-Center Experience
    (2022) Hasbay, Bermal; Aytac, Huseyin Ozgur; Bolat, Filiz Aka; 35059589
    Objective: Breast carcinomas with neuroendocrine (NE) differentiation are extremely rare. The aim was to discuss breast cancer cases with NE differentiation in the light of World Health Organization 2019 classification and literature information. Material and Methods: The pathology records of 56 cases diagnosed as neuroendocrine tumor (NET) and/or breast cancers with NE differentiation presenting to a single center between January 2010 and June 2020 were evaluated. The patients were evaluated in terms of age, tumor size, location, histological grade, hormone profiles (ER, PR, HER2), guideline American Joint Committee on Cancer, lymph node status, stage, metastases, progression, survival, radiological features, surgery type and therapy modality. Results: The age of the patients ranged from 34 to 81 years. Average tumor size was 2.3 cm. Median (range) follow up time was 31.5 (1-73 month). Metastatic lymph nodes were found in 20 cases. In our series, NE differentiation mostly accompanied invasive carcinoma of no special type, less frequently solid papillary carcinoma, and mucinous carcinoma. Four patients had a history of neoadjuvant chemotherapy. Response to treatment was very poor in all four cases. Synaptophysin and chromogranin were positive in 38 cases. No correlation was found among tumor size, grade, age, lymph node status, and presence of distant metastasis in our series. Conclusion: Clinical features and morphology may not help to distinguish NET from other subtypes of breast cancer. Therefore, the morphologic findings of a nested or trabecular architecture, nuclear or cytoplasmic features of NE differentiation, mucin production, or solid papillary growth pattern should prompt a pathologist to order NE markers.

    What is the predictive value of preoperative CA 125 level on the survival rate of type 1 endometrial cancer?
    (2021) Baran, Safak Yilmaz; Alemdaroglu, Songul; Durdag, Gulsen Dogan; Simsek, Seda Yuksel; Bolat, Filiz Aka; Kose, Fatih; Celik, Husnu; 0000-0001-5874-7324; 0000-0003-4335-6659; 0000-0003-3191-9776; 0000-0002-0156-5973; 32979897; AAI-8400-2021; AAK-7016-2021; G-4827-2016; AAL-1923-2021
    Background/aim: To investigate the utility of preoperative serum cancer antigen 125 (CA 125) levels in type 1 endometrial carcinoma (EC) as a marker for determining poor prognostic factors and survival. Material and methods: All patients with endometrial cancer, who had been treated between 2012 and 2020, were retrospectively reviewed, and finally, 256 patients with type 1 endometrium carcinoma were included in the study. The relationship between the clinicopathological characteristics, CA 125 level, and survival rates were analyzed. The cut-off value for the preoperative serum CA 125 level was defined as 16 IU/L. Results: The median serum CA 125 levels were significantly higher in patients with deep myometrial invasion, lymph node metastasis, lymphovascular space invasion, cervical stromal and adnexal involvement, advanced stage, positive peritoneal cytology, recurrence, and adjuvant therapy requirement. Serum CA 125 cut-off values determined according to clinicopathologic factors ranged from 15.3 to 22.9 IU/L (sensitivity 61%-77%, specificity 52%-73%). The disease-specific survival rate was significantly higher in patients with CA 125 levels < 16 IU/L (P = 0.047). Conclusion: The data showed that choosing a lower threshold value for the CA 125 level (16 IU/L) instead of 35 IU/L, could be more useful in type 1 EC patients with negative prognostic factors.

    Clinicopathologic importance of atypical glandular cells in cervico-vaginal cytology
    (2020) Yuksel, Seda; Simsek, Erhan; Yetkinel, Selcuk; Alemdaroglu, Songul; Bolat, Filiz Aka; Celik, Husnu; 0000-0003-4335-6659; 0000-0002-2165-9168; 31450881; AAI-8400-2021; AAL-1530-2021; AAK-7016-2021
    Objective: To analyze the histopathologic outcomes of patients with atypical glandular cells (AGC) in cervicovaginal cytology examinations. Material and Methods: Patients with AGC in cervicovaginal cytology were included in this study between March 2011 and March 2018 and patient data were collected retrospectively among all cytology results. AGC classification of cervicovaginal cytology were based on the Bethesda 2001 classification system. Results: The total prevalence of cervical epithelial cell abnormality and AGC were found as 9.2% and 0.2%, respectively, in the study cohort. AGC-favor neoplasia (AGC-FN) was the subgroup of AGC, with the highest malignancy rate with 62.5% (p=0.06). The incidence of malignancy in the postmenopausal group (33.3%) was detected higher than in the premenopausal group (8.3%) (p=0.07). Conclusion: The probability of malignancy in AGC-FN cytology is more commonly associated with malignancy in the postmenopausal group. Therefore, histopathologic examination is strongly recommended in these patients with AGC smears because of the high risk for malignancy in this group.

    Male Breast Cancer: Clinicopathological, Immunohistochemical and Radiological Study
    (2020) Hasbay, Bermal; Bolat, Filiz Aka; Aytac, Huseyin Ozgur; Kus, Murat; Pourbagher, Aysin; 0000-0001-6529-7579; 0000-0002-3583-9282; 32525214; AAJ-7870-2021; AAJ-7913-2021
    Objective: To evaluate the pathological and radiological features, immunohistochemical profile and treatment methods of primary male breast carcinoma cases diagnosed at our center. Material and Method: The pathology archive between 2006 and 2019 was reviewed and the data of 27 male patients diagnosed as primary breast cancer were retrospectively evaluated. Results: The age of the patients ranged between 40-86 years. The left breast was involved in 17 patients. The mean tumor diameter was 2.35 +/- 1.09 cm. Of the 27 cases, 8 were dead and 19 were alive. The mean follow-up duration was 37.45 +/- 24.84 months. The mean estimated life expectancy was 65 +/- 14.7 months. The most common complaint was a swelling in the breast. The time interval between the onset of complaints and admittance to hospital ranged from three months to two years. The most common histopathological diagnosis was invasive carcinoma - no special type. The most common surgical procedure was mastectomy with lymph node dissection. Nine patients had metastatic lymph nodes. In terms of the hormone profiles, 24 were Estrogen receptor positive, 21 were Progesterone receptor positive and six were Her2/neu positive. Three patients had triple-negative tumors. Conclusion: Male breast carcinoma is a rare disease but its frequency has been increasing recently. As breast cancer is more commonly attributed to women, the diagnosis is usually delayed until later stages in males. Public awareness should therefore be increased and breast cancer should be considered in the differential diagnosis especially in the presence of breast swelling and complaints related to the breast skin so that the appropriate biopsy can be obtained without delay.

    Not Otherwise Specified-Type Sarcoma of Breast with CD10 Expression: Case Report
    (2019) Hasbay, Bermal; Bolat, Filiz Aka; Aslan, Hulya; Aytac, Huseyin Ozgur; 31620687
    Primary breast sarcomas are very rare and account less than 1% of invasive breast carcinomas. Primary sarcomas of breast are leiomyosarcoma, angiosarcoma, liposarcoma, fibrosarcoma, rhabdomyosarcoma, malignant peripheral nerve sheath tumor and pleomorphic sarcoma. Recently, a new CD10 positive group of sarcoma was identified. These tumors cannot be classified as a soft tissue sarcoma and show diffuse strong positive staining pattern with CD10 (NSCD10). Herein we report clinical and morphological characteristics of two cases diagnosed with not otherwise specified-type sarcoma with CD10 expression by histologically and immunohistochemical findings with the literature. NSCD10 shows similarity with leiomyosarcoma and sarcomatoid-type metaplastic carcinoma histomorphologically among specific sarcomas of breast. CD10 expression should be taken into consideration in the presence of not diagnosed and not specified tumors and CD10 should be added to the immunohistochemical panel.

    Myofibroblastoma of the Breast
    (2015) Aytac, Huseyin Ozgur; Bolat, Filiz Aka; Canpolat, Tuba; Pourbagher, Aysin; 28331720
    This study aimed presenting a case of a 64-year-old woman with a rare diagnosis of myofibroblastoma (MFB). MFB is one of the rare, benign, spindle-like stromal tumors arising from the connective tissue of the breast. MFBs are often confused with fibroadenomas and hamartomas because of their benign characteristic appearance on breast imaging and are diagnosed after excisional biopsies. Their differential diagnosis with malignant neoplasia of the breast is important because of their wide morphological spectrum. Our case also demonstrated a breast mass with benign imaging characteristics and a needle core biopsy revealing a benign, spindle-like stromal tumor. The pathological examination performed after the excision of the lump demonstrated a collagenous-/fibrous-type MFB. This case report emphasizes the rare but important place of MFB variants of the breast in the differential diagnosis of breast mass.

    Huge Neck Masses Causing Respiratory Distress in Neonates: Two Cases of Congenital Cervical Teratoma
    (2016) Gezer, Hasan Ozkan; Oguzkurt, Pelin; Temiz, Abdulkerim; Bolat, Filiz Aka; Hicsonmez, Akgun; 0000-0002-4635-2613; 0000-0001-8789-6003; 25176284; J-3197-2013; A-4719-2018
    Congenital cervical teratomas are rare and usually large enough to cause respiratory distress in the neonatal period. We present two cases of congenital huge cystic neck masses in which distinguishing cervical cystic hygroma and congenital cystic teratoma was not possible through radiologic imaging techniques. Experience with the first case, which was initially diagnosed and treated as cystic hygroma by injection sclerotherapy, led to early suspicion and surgery in the second case. The masses were excised completely and histopathologic diagnoses were congenital teratoma in both patients. Our aim is to review congenital huge neck masses causing respiratory distress in early neonatal life to highlight this dilemma briefly with these interesting cases.

    Intractable pain following core decompression caused by salmonella septic arthritis
    (2016) Beyaz, Salih; Guler, Umit Ozgr; Cinar, Bekir Murat; Bolat, Filiz Aka; 0000-0002-7906-5039; 0000-0002-5375-635X; 0000-0002-5788-5116; 0000-0002-5788-5116; AAL-4474-2021; O-7590-2017; K-8820-2019; M-2609-2013
    Glucocorticoids (GC), often used in the treatment of diseases caused by autoimmune mechanisms, are the most common nontraumatic causative factor of femoral head avascular necrosis (FHAN). FHAN is, in turn, the most common cause leading to orthopedic surgery in patients using GCs. As GCs suppress the immune system, patients experience increased susceptibility to infections, including FHAN, which has a similar clinical manifestation with septic arthritis. In rare cases, septic arthritis may be caused by salmonella in patients using GCs. Core decompression is the gold standard in the treatment of early stage FHAN. We report a 28-year-old male patient with multiple sclerosis (MS) presenting with the complaints of hip pain. The patient had been treated with two megadoses of steroids. FHAN was considered due to X-ray and MRI findings. The patient underwent core decompression (CD) and salmonella bacteria growth was found in the hip puncture culture. Avascular necrosis associated with septic arthritis was determined. The patient was re-operated and irrigation and debridement for synovial tissues were performed two days following the first operation. While the association of septic arthritis with causative Salmonella and FHAN is rare except in sickle cell patients, septic arthritis must be considered and ruled out in patients who have previously undergone CD and did not show expected relief in early stage FHAN.

    (2017) Bolat, Filiz Aka; Colakoglu, Sule; Coban, Gonca; 0000-0002-3285-5519; AAI-9974-2021
    Assessment of Human papillomavirus (HPV) prevalence and genotype distribution is important for monitoring the impact of prophylactic HPV vaccination. This study aimed to demonstrate the HPV prevalence and type distribution in women from the Baskent University Adana Dr. Turgut Noyan Practice and Research Center. Cervical specimens from 268 women aged 22-68 years were collected between April 2014 and November 2015. Histopathological examinations were performed for 146 women. HPV DNA was amplified by PCR and HPV and genotyping was undertaken using the Roche (R) linear array detection kit. In total. 124 out of 268eligible samples (46.31%) tested positive for HPV. with the majority of these [84/124 (67.7%1] having high-risk (HR) HPV infection: 20.9% were positive for HPV16 (n=261, and 4% for HPV18 (n=5) HPV type-specific prevalence was 63.9% 53.39 and 80% among cervical intraepithelial neoplasias (CIN) Grades respectively. The coverage of other HR-HPV genotypes apart from 16. included HPV31. 45. 51, 53, and 56 in high-grade cervical lesions. In conclusion, HPV-16 was identified as the main HPV genotype associated with cervical disease in our hospital. The study reports the identification of high-and low-risk HPV genotypes as well as the prevalence of multiple HPV infections.
