granulosa cell tumor

 [gran″u-lo´sah]
an ovarian tumor originating in the granulosa cells, the solid mass of cells surrounding the graafian follicle; it may be associated with excessive production of estrogen, inducing endometrial hyperplasia with menorrhagia.

gran·u·lo·sa cell tu·mor

a benign or malignant tumor of the ovary arising from the membrana granulosa of the vesicular ovarian (graafian) follicle and frequently secreting estrogen; it is soft, solid, white or yellow, and consists of small round cells sometimes enclosing Call-Exner bodies; larger lipid-containing cells may be present.
Synonym(s): folliculoma (1)

granulosa cell tumor

Gynecology A sex cord tumor of older ♀ that comprises 1-2% of ovarian neoplasms, which is 'driven' by unopposed estrogen stimulation; the endometrium of Pts with GCTs often has cystic hyperplasia and 5-25% of Pts also have a concomitant well-differentiated endometrial CA

Neonatal juvenile granulosa cell tumor of the testis
[7] In the present study, among 7 sex cord stromal tumors encountered, 4 were diagnosed as adult granulosa cell tumors. All the cases presented with mass per abdomen, while one patient gave history of post-menopausal bleeding, these tumors were bilateral while one granulosa cell tumor was unilateral.
Non epithelial tumors of ovary
This is one of the best known ovarian tumors and has taken its place in their classification system for decades now but ironically, at least in my opinion, is a rare tumor that has received perhaps disproportionate interest in the literature in part because of its being 1 of the 2 often estrogenic neoplasms of the ovary, the other being the granulosa cell tumor. If one is stringent in diagnosing thecoma, it will be much less often encountered than the adult granulosa cell tumor.
