Granulosa cell tumours are sex cord stromal tumours of the ovary which accounts for 1-2% of all ovarian malignancies. We present a case of a 22 yrs old unmarried girl with chief complaints of dysmenorrhoea for last 4 months. There were no other symptoms and her general physical examination revealed no abnormality. Ultrasonography showed a simple ovarian cyst of 7 × 8 cm in right adnexa with normal Doppler flow and no ascites. Her tumour markers were negative. Per-operative uterus and left sided ovary and upper abdomen was normal. Right ovary showed a simple unilocular cyst of around 8 × 8 cm and right ovarian cystectomy done. Surprisingly histopathological examination of cyst wall revealed granulosa cell tumour. Immunohistochemical staining was found to be positive especially with inhibin. Staging laparoscopy with peritoneal wash, multiple peritoneal biopsy with right sided salpingo-oopherectomy, left sided ovarian biopsy and dilatation and curettage was done. Cytological and histopathlogical examination were found to be normal. Post operatively patient received chemotherapy because cyst wall was ruptured per-operatively and patient is doing fine and disease free till now.
