Sertoli-leydig cell tumor of ovary- a diagnostic dilemma.

Sertoli Leydig Cell Tumours (SLCTs) are rare, unilateral, sex cord stromal tumours of ovary, which constitute less than 1% of all the ovarian neoplasms. These tumours can be functionally diverse and they may have heterologous elements. We aim to report a case of a 25-year- old woman who presented with suprapubic pain of 5 days duration, a unilateral adnexal mass, hypertestosteronism without virilization. Intraoperative frozen section of the unilateral salpingo-oophorectomy specimen was suggestive of granulosa cell tumour. Histopathological examination, supplemented with alpha-inhibin immunohistochemistry, was diagnostic of Meyer's type II SLCT. Clinical presentation, pathology and the diagnostic pitfalls in the present case have been presented with a brief review of literature.
