MSH: A neoplasm composed entirely of GRANULOSA CELLS, occurring mostly in the OVARY. In the adult form, it may contain some THECA CELLS. This tumor often produces ESTRADIOL and INHIBIN. The excess estrogen exposure can lead to other malignancies in women and PRECOCIOUS PUBERTY in girls. In rare cases, granulosa cell tumors have been identified in the TESTES.,NCI: A type of slow-growing, malignant tumor that usually affects the ovary.,NCI: A neoplasm of the ovary (or testis), originating from granulosa cells for which the malignancy status has not been established.,NCI: A slow-growing, malignant tumor, characterize by the presence of granulosa-like cells and Call-Exner bodies, that is almost always found in the ovary. In rare cases, it has also been found in the testicle. There are two types of granulosa cell tumor that can be distinguished under the microscope: the adult and the juvenile. The testicular juvenile granulosa cell tumors are perhaps the most common congenital testicular neoplasms.
