Dermal angiomyoma of the upper extremity.

Twenty-four of a series of 85 dermal angiomyomata were located in the upper extremity distal to the elbow. Eleven occurred in the right arm and 13 appeared in the left. Women exceeded men by 13 to 1 in number. The greatest number occurred in the 40 to 70 year age group. One case recurred as a leiomyosarcoma. This report is intended to bring this lesion to the attention of the surgeon in the differential diagnosis of painless masses of the hand, wrist, or forearm.
