Sclerosing stromal tumor (SST), an extremely rare benign stromal tumor, is a subtype of sexcord stromal tumors of the ovary. In this report, radiological and histopathological features of the case are briefly discussed in the light of the literature. A 23-year-old female patient with a right adnexal mass showing cystic and solid components on abdominal ultrasonography, was referred to our center's obstetrics clinic for further diagnosis and treatment. The patient had no blood hormonal abnormalities and also had a request for gender change. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed after intraoperative examination of the mass. The diagnosis of sex cord stromal tumor was given intraoperatively and later histopathological examination revealed a pseudolobular pattern formed by collagenous and edematous hyper-hypocellular areas and marked vascular proliferation. Morphological and immunohistochemical findings of the right ovarian tumor was consistent with "SST". Radiologically, SSTS are diagnosed as a malignant tumor because of the most of them are highly vascular solid masses. For this reason, intraoperative histopathological examination is crucial to prevent over-treatment, because SST has a benign biological behavior and occurs in young patients whose conservative surgery is required.
