Angiomyofibroblastoma-like tumors (cellular angiofibroma).

Angiomyofibroblastoma-like tumor (cellular angiofibroma) is a rare, circumscribed, slow-growing mesenchymal tumor that occurs predominantly in the vulva, perineum, and pelvis of women. We report two cases of this tumor in men arising as paratesticular masses of the scrotum, summarize the history of this tumor, and discuss why efforts should be made to differentiate it from aggressive angiomyxoma. Recommended treatment is complete surgical excision with long-term follow up exams, as local recurrence may occur many years after resection of the lesion.
