Leiomyoma of digit of hand: Report of three cases with literature review

Leiomyoma is a benign tumor of smooth muscle origin most common in areas of the body with abundant smooth muscle including the gynecologic, genitourinary, and gastrointestinal system. Leiomyoma outside of these locations is believed to arise from vascular smooth muscle and arrector pili muscles. Leiomyoma of an extremity is a rare diagnosis, especially when present in a digit of the hand due to the paucity of smooth muscle in this location. We report three cases of leiomyoma of a digit of the hand.
