title: Acral arteriovenous tumor. A clinicopathologic review.
abstract: We reviewed 47 cases of a distinctive, benign vascular tumor, acral arteriovenous tumor. Study of the clinical histories of patients with this tumor emphasized the difficulty of making a clinical diagnosis. Most of the tumors were asymptomatic and were found in generally healthy middle-aged or elderly male patients. Distribution was acral; 79% of the tumors were located on the head or extremities. Histologic study showed a component of capillary nevus in some cases in addition to the typical venous and arteriovenous channels.
