Piloleiomyoma is a benign smooth muscle tumor which arises from the erector pilorum muscles. The lesions can be solitary or multiple. They are painful, tender to cold, touch and pressure and sensitive to emotions. The authors report the case of a man with intradermal nodules composed of smooth muscle fibers. Immunohistochemical staining was positive for desmin and actin, thus confirming the diagnosis.
