title: Nevus leiomyomatosus systematicus.
abstract: Leiomyomas of the skin are classified as pilar, genital, or angioleiomyoma depending on the site of origin. Pilar leiomyomas are the most common form, and usually multiple tumors are found in a single patient. An unusual variant of multiple pilar leiomyoma is nevus leiomyomatosus systematicus, a descriptive term used when tumors are wide-spread and patterned, suggesting a nevoid condition. Many of the large pilar tumors are painful and require surgical excision for relief of symptoms.
