Gynandroblastoma. Report of an unusual ovarian tumour and literature review.
Gynandroblastoma is a rare variant of ovarian sex cord stromal tumours that demonstrates morphological evidence of both male and female differentiation. We report a new case of gynandroblastoma in a 22-year-old nulliparous female with a history of menstrual disturbance. Physical examination disclosed a painless pelvic mass measuring 20 cm across with normal secondary sex characteristics, and no signs of virilisation. Histological examination of the surgically resected primary tumour revealed a predominant adult granulosa cell component admixed with a minor Sertoli cell component that did not exceed 20% of the tumour. Immunohistochemical analysis showed positive immunostaining of Sertoli cell areas with inhibin. The final diagnosis was gynandroblastoma. The post-operative course was uneventful and there was no evidence of recurrence during the 9-month follow-up period.
