Sertoli Leydig Cell Tumour Initially Misdiagnosed as Polycystic Ovarian Syndrome and Congenital Adrenal Hyperplasia: A Case Report.

Sertoli-Leydig cell tumor of the ovary is an unusual neoplasm that belongs to a group of sex cord-stromal tumors of the ovary and accounts for less than 0.5% of all primary ovarian neoplasms. They are often characterized by the presence of mass with androgen production and signs of virilization. Due to the substantially low incidence of Sertoli-Leydig cell tumors, information on clinical behavior, prognostic factors, and optimal management arelimited. Here in, we report a case of aprimary ovarian Sertoli-Leydig cell tumor in a 21-year-old student, previously diagnosed to have polycystic ovarian syndrome and subsequently congenital adrenal hyperplasia, who presented with a large abdominal mass and features of virilization along with elevated serum testosterone levels. Fertility sparing unilateral salpingo-oophorectomy was done and adjuvant chemotherapy was given after histopathology showed moderate to poorly differentiated Sertoli-Leydig cell tumor. Following surgery, her features of hyperandrogenism resolved and serum testosterone levels returned to normal.
