Cutaneous piloleiomyomata.

A 49-year-old man presented with an eight-month history of intermittently painful, subcutaneous nodules that were increasing in size, number, and pain intensity. A biopsy specimen showed smooth muscle proliferation, which also stained positive for actin, and was consistent with piloleiomyoma. The patient was placed initially on gabapentin and then nifedipine with very limited success in pain control. The lesions continued to proliferate, and the patient was referred to surgery for excision.
