Familial cutaneous and uterine leiomyomas: case report.

Cutaneous leiomyomas are rare, benign tumors arising from the arrectores pilorum muscles of the skin, the tunica dartos of the scrotum, muscles of the areola of the nipple, and vulvar or vascular smooth muscles. Multiple cutaneous leiomyomas originate from the arrectores pilorum muscles of the skin (piloleiomyomata cutis). Occasionally, they seem hereditary and may be associated with uterine myomas.
