Glomus tumor is not always digital: case report

Abstract

Glomus tumors are benign vascular neoplasms that arise from specialized dermal arteriovenous anastomoses called glomus bodies. Glomus tumors most commonly occur in the hand and specifically the subungual region of the distal phalanx. however, a review of the literature suggests that extradigital glomus tumors may occur more often than is generally recognized. A subcutaneous glomus tumor of the forearm is a very rare occurrence and only a few cases have been reported in the literature.we report a 40 year-old man with a 5-year history of a painful subcutaneous nodule of his right  forearm. Clinically differential diagnosis was and benign  malignant skin tumor. Surgical excision was performed. Histopathological examination, and Immunohistochemistry confirmed the diagnosis of Glomus tumor.
