Abstract

Angiomyofibroblastoma of the male genital tract is a rare tumor with only 20 cases reported in the literature to date. We report three cases in males aged from 23 to 44 years. They presented with painless inguinal, scrotal and perineal masses, ranging from 3 to 8 cm in diameter. On microscopic examination the tumors were composed of small spindle cells without atypia in a fibrous and myxoid stroma. There were scattered mononuclear inflammatory cells around capillaries. Immunohistochemical studies showed positive staining of the tumor cells for vimentin, and weak reactivity for CD34, bcl-2, CD99, EMA and CD117. Some tumor cells expressed estrogen receptors in all three cases, and progesterone receptors in only one case. There was no recurrence with a follow-up ranging form 12 to 21 months. Angiomyofibroblastoma of the male genital tract is a benign often hormone-dependent tumor. Its histogenesis is still unclear. It has to be distinguished from aggressive angiomyxoma and myxofibrosarcoma.
