A Solitary Volar Extradigital Glomus Tumor Mimicking a Painful Ganglion

Abstract

Glomus tumors are neoplasms arising from the glomus body, which regulate skin temperature. They are mostly benign tumors and present in the subungual area of a distal phalanx. However, they can occur in extradigital location, and they may not be typical of intradigital glomus tumors. This makes it difficult to diagnose extradigital glomus tumors. We report a volar extradigital tumor mimicking a painful ganglion with a literature review.
