Pilar leiomyoma: a case report and review of the literature.

Abstract

Pilar leiomyoma is a benign smooth muscle tumor arising from the arrectores pili muscles associated with the hair follicles of the skin. The multiple biopsies and pathological consultations needed to obtain a diagnosis attest to the rarity of the disease and the difficult histological picture, which often requires an expert pathological consultation. Although a benign soft-tissue tumor, pilar leiomyoma often requires therapeutic intervention to alleviate pain or sensitivity. Medical therapy has been tried with some success to improve the pain and discomfort. The only potentially curative option, however, remains surgical excision. Although complete surgical excision may not be attained, it may achieve substantial symptomatic improvement.
