Cavernous hemangioma of the cephalic vein.

Although capillary and venous hemangiomas are common problems in children, cavernous hemangiomas of extremity veins in adults are unusual. Successful operative removal of a cavernous hemangioma in the right forearm of a 37-year-old man is described. To the author's knowledge, such lesions in named upper-extremity veins have not previously been reported.
