    (2020) Kucukkosmanoglu, Ilknur; Eren Karanis, Meryem Ilkay; Altunkeser, Aysegul; Koksal, Hande
    Aim: Breast hamartomas are uncommon benign lesions that constitute 4.8% of benign breast tumors; they consist of mammary ducts and lobules, fatty tissue, and fibrous tissue. The aim of this study was to determine the clinical and pathological characteristics of breast hamartomas diagnosed by surgical resection and to examine the accompanying lesions. Material and Methods: Patients who underwent breast surgery between January 2013 and January 2018 at Konya Education and Research Hospital and who were diagnosed as having breast hamartomas were reviewed retrospectively. Results: Seven breast hamartomas were identified. All of them were female. The mean age was 45 years. The mean tumor size was 3.9 cm. Most of the lesions were located in the right breast (57.1%). All the hamartomas appeared in the upper part of the breast. Five of the seven cases were admitted with a painless palpable mass in the breast (71.4%). Three of the seven cases were myoid hamartomas. The type of lesion most commonly associated with breast hamartomas is cyst formation. Pseudoangiomatous stromal hyperplasia, columnar cell hyperplasia, and ductal epithelial hyperplasia are also common. Ductal epithelial hyperplasia and columnar cell hyperplasia were observed in all the myoid hamartomas. Ductal carcinoma in situ was detected in one case; it was also a myoid hamartoma. Conclusions: Breast hamartomas are accompanied by many types of lesions such as fibrocystic changes, adenosis, ductal epithelial hyperplasia, and pseudoangiomatous stromal hyperplasia. In addition to these lesions, columnar cell hyperplasia was also identified. Malignancies are rarely detected in breast hamartomas; however, one case of ductal carcinoma in situ in a myoid hamartoma was detected.

    Our sentinel lymph node experience in patients diagnosed with DCIS and microinvasive breast carcinoma
    (2021) Bayramoglu, Zeynep; Omeroglu, Ethem; Koksal, Hande; Eryilmaz, Mehmet Ali; Unlu, Yasar
    Aim: Along with the increased availability of radiologic imaging methods, early identification of tumor tissue, and patient surveillance programs; ductal carcinoma in situ (DCIS) and microinvasive DCIS became more commonly identified in the tru-cut biopsy specimens and resected samples of patients. Pathological examinations of the excision materials from these patients reveal invasive tumors, microinvasions or DCIS alone. Recently, it has become debatable whether to perform a sentinel lymph node biopsy (SLNB) in patients diagnosed with DCIS or microinvasive DCIS. In this present study, we evaluated the diagnosis made by examining the excision material, any presence of lymph node metastases, and the relationship of hormone profile to the presence of metastases in the patients diagnosed with DCIS or microinvasive DCIS by the examination of tru-cut biopsy specimens. Based on our study results, we discussed the requirement for SLNB in patients with a tru-cut diagnosis of DCIS or microinvasive DCIS. Materials and Methods: The study included 172 patients, who underwent surgical excision and SLNB after receiving a tru-cut biopsy diagnosis of DCIS and microinvasive DCIS in our hospital from the year 2010 to 2018. Results: Tru-cut biopsy diagnoses were DCIS and microinvasive DCIS in 69.8% (120 patients) and 30.2% (52 patients) respectively. SLNB metastases were identified in 35.8% (n=43) of the DCIS positive patients and 44.2% (n=23) in the microinvasive DCIS positive patients. The diagnosis of invasive ductal carcinoma after mastectomy was made at a rate of 90.0% (n=108) among the DCIS positive patients and 92.3% (n=48) among the microinvasive DCIS positive patients. Conclusion: SLNB metastases were found in 35.8% (n=43) and 44.2% (n=23) of the DCIS positive patients and microinvasive DCIS positive patients, respectively. We conclude that SLNB should be favorably proper to perform in the patients with tru-cut diagnoses of DCIS and microinvasive DCIS because a high rate of SLNB metastases was detected in our DCIS and microinvasive DCIS patients and a high rate of invasive ductal carcinoma diagnosis was made after examining the excision material of these patients.
