Gynandroblastoma: a rare ovarian tumour with an unusual clinical presentation.

Gynandroblastoma is a rare ovarian mixed sex cord stromal tumour with very few cases reported in literature. These tumours are considered to be potentially malignant. Here a case of gynandroblastoma occurring in a 30-year female is reported who gave history of irregular menstrual bleeding and pain abdomen, there were no signs of virilisation. Computed tomography scan showed a left adnexal mixed density pelvic mass suggesting malignant ovarian tumour. Histological study revealed, the tumour was composed of mixed sex cord elements with predominantly intermediate differentiated Sertoli-Leydig cell component and a second adult type granulosa cell component.
