An unusual congenital leiomyoma.
Cutaneous leiomyomas are rarely encountered at birth. In their usual form they appear as discrete dermal papules or nodules with a pink or brown discoloration of the overlying skin. We examined an infant with an unusual mass attached to the right heel at birth. Histologically, the lesion was a leiomyoma. It apparently represented a bizarre proliferative anomaly of smooth muscle occurring during fetal development.
