Glomus tumor of the ovary masquerading as granulosa cell tumor: case report.
A solid right adnexal mass in a 73-year-old woman bled profusely with mobilization mimicking a granulosa cell tumor. There was almost complete replacement of the ovary by a circumscribed, 4.0 cm tumor with a hemorrhagic, solid cut surface. Morphologic and phenotypic correlation supported a diagnosis of glomus tumor. Large gaping vessels and small sinusoidal-type vessels formed an anastomotic vascular network with an inner endothelial lining (CD31+/CD34+) and an outer layer of glomocytes (actin+/desmin-/inhibin-). The hemangiopericytoma-like vasculature accounted for bleeding during surgery.
