Unicystic granulosa cell tumor: a case report.

Granulosa Cell Tumors (GCT) constitutes 1.5% to 3.5% of all primary ovarian neoplasms. They may be solid, cystic or both. Unilocular cystic GCT are very rare. We report here a case of 32 years female with unicystic GCT in which the distinction from follicular cyst was difficult and was made by carefully examining the lining of the cyst,which showed occasional multiple layers of granulosa cells with a few Call-Exner bodies.
