An Extradigital Glomus Tumor of the Median Antebrachial Vein.

Glomus tumors are benign vascular neoplasms that arise from specialized dermal arteriovenous anastomoses called glomus bodies. These tumors are most often found in the digital pulp and subungual region of the fingertips; however, a review of the literature suggests that extradigital glomus tumors may occur more often than is generally recognized. Although most extradigital glomus tumors arise within subcutaneous tissues, glomus tumors have occasionally been found within bones, nerves, and blood vessels.
