Congenital pilar leiomyoma.

Piloleiomyomas are benign smooth muscle tumors arising from the arrectores pilorum muscles in the skin. They usually occur as multiple firm dermal nodules located on the extremities and trunk. Solitary lesions are rare. Leiomyomas usually develop during adolescence or early adult life. Congenital pilar leiomiyoma is an extremely rare entity. We present a case of congenital solitary pilar leiomyoma located on the face.
