Postmenopozal kadinda az diferansiye sertoli-leydig hücreli tümör [Poorly differentiated ovarian sertoli-leydig cell tumor in a postmenopausal woman: Case report]

70-75% of Sertoli-Leydig cell tumors (SLCT) are diagnosed at before age of 40, and less than 10% takes place before menarche and following menapouse. We report a case of right adnexal mass in a 59 year-old postmenapousal woman who presented with vaginal bleeding. Sex-cord stromal tumor was diagnosed at peroperative frozen section assesment. Staging surgery consisting of peritoneal biopsies, omentectomy and pelvic paraaortic lymph node dissection was performed. In histopathologic assesment of the slides which were prepared from solid-cyctic areas of the mass, revealed immature sertoli cells forming tubules and a wide sarcomatoid differantiation. Immunhistochemically, neoplastic cells stained strongly and diffusely positive with CD 56, focal positive with calretinin and inhibin. Poorly differentiated SLCT was diagnosed with the consideration of both histopathologic and immunhistochemical findings. Poorly differantiated SLCT are unusual sex cord stromal neoplasms of ovary of which differantial diagnosis should include spindle cell neoplasms. © Copyright 2016 by Türkiye Klinikleri
