ABSTRACT
Vascular tumors of the female genital tract, especially those arising in the ovary, are very rare although the ovary has a rich vascular supply. We report a case of cavernous hemangioma of the right ovary in a 48-year-old woman who un-derwent total abdominal hysterectomy and right salpingo-oophorectomy for symptomatic uterine leiomyomas. At laparotomy, multiple uterine nodules consistent with leiomyomas were detected but the right ovary was unremar-kable. Macroscopically, two intramural leiomyoma nodules, a corpus luteum cyst, a cortical cyst, multiple corpora albicans, and a paratubal cyst were ob-served. Microscopical examination revealed an incidental cavernous hemangi-oma, consisting of multiple thin-walled vascular channels, filled with red blood cells in the cortex and medulla of the right ovary, which had not been grossly appreciated. These vascular channels were lined by a single layer of flattened endothelial cells that showed strong immunoreactivity for CD31, CD34, and factor VIII-related antigen.
