Abstract

Unilocular cystic granulosa cell tumors (UCG) are extremely rare. Due to the relatively small mass of the tumor available for histologic examination, diagnosis of UCG is not easy. Here we present a case of UCG in a 54-year old female. A 12x10 cm unilocular cystic mass was identified in the right ovary. The tumor was thin-walled and consisted of a single large cavity with a smooth internal surface. In most areas there were no cells lining the cyst, however, in focal areas the unilocular cyst was lined by one or more layers of uniform granulosa cells, forming Call-Exner bodies. A diagnosis of UCG was made after multiple sections were examined. A careful histologic examination is required for the correct diagnosis of UCG.
