Enxtraoviarian granulosa cell tumor: a case report
AbstractExtraovarian granulosa cell tumor (GCT) is a very unusually tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge. One such rare case of extraovarian granulosa cell tumor was encountered in a 60-year-old female patient who presented with a large intra-abdominal mass. Computerized tomography revealed a large retroperitoneal mass measuring 11 x 10 x 8cm in size. Her past medical history was irrelevant. She underwent exploration laparotomy and the mass was excised. Histopathological examination of the excised mass showed features of adult-type granulosa cell tumor.The tumor showed positivity for inhibin while epithelial membrane antigen was negative thus confirming the diagnosis of granulosa cell tumor. A diagnosis of extraovarian granulosa cell tumor can only be done after excluding any previous history of granulosa cell tumor of the ovary. Immunostains help to differentiate granulosa cell tumors from other neoplasms.
