Vascular leiomyomas in the hand.

Vascular leiomyomas or angioleiomyomas are benign solitary smooth muscle tumors that occur uncommonly in the hand. The peak incidence is in the third to fifth decades of life, and men are more often affected than women. This tumor is rarely diagnosed before surgery. The usual treatment is simple excision of the mass and ligation of feeder vessels. Although the tumors occur anywhere in the hand, there are only two previous cases of vascular leiomyoma involving the digital artery. A recent case of this tumor involving a digital artery documented by arteriography and treated by excision of the mass and end-to-end anastomosis of the artery is presented. The authors review their experience with vascular leiomyomas in the hand and present four cases along with a review of 105 cases found in the English literature.
