Case for diagnosis: (unilateral multiple piloleiomyoma).

Piloleiomyoma is a benign neoplasm arising from the erector pilorum muscle in the skin. It occurs in young adults of both genders. Lesions can be single or multiple and more frequently involve extremities. Pain may occur spontaneously or after physical stimulation. We describe a case of unilateral multiple piloleiomyoma in a young woman, complaining of itching lesions.
