It is characterized by the presence of granulosa cells that comprise at least ten percent of the cellular population. The granulosa cells are often found in a background that contains theca and fibrous cells. There are two major subtypes recognized, adult and juvenile granulosa cell tumor. Clinically, patients may present with an abdominal mass. Symptoms depend on the patient's age. The most important indicator of prognosis is tumor stage. Age over forty years at the time of the initial diagnosis, large tumor size, bilaterality, cellular atypia, and increased mitotic activity are factors indicating a potentially aggressive clinical course and relative poor prognosis. granulosa theca cell tumour of the ovary ovary granulosa cell tumour granulosa theca cell tumor of the ovary ovarian granulosa cell neoplasm granulosa cell neoplasm of ovary ovarian granulosa cell tumor MEDGEN:277970 adult granulosa cell tumour of the ovary granulosa cell tumour of the ovary granulosa theca cell tumor NCIT:C6261 SCTID:254863004 granulosa theca cell tumour GARD:0027911 granulosa cell tumor of the ovary UMLS:C1370419 ovary granulosa cell tumor MONDO:0023283 granulosa cell neoplasm of the ovary ovary
