Giant vascular leiomyoma with extensive calcification in the forearm.
Vascular leiomyoma or angioleiomyoma is a benign solitary smooth muscle tumor that occurs in the forearm relatively rarely. Most of these tumors are composed of venous vessels, but in some reports small arteries have been traced in the tumors. We describe a 72-year-old man who presented with a slowly enlarging mass in the distal forearm with extensive calcification. Our case had the following three peculiarities compared with common findings in patients with a vascular leiomyoma: (1) elderly age; (2) giant size tumor; and (3) tumor with extensive calcification. The ulnar artery was involved in the tumor. Simple excision of the tumor, including the ulnar artery, was performed. There was no recurrence and no cold intolerance.
