Glomus tumors are rare tumors of the arteriovenous junction that play a role in temperature regulation. They are most commonly found in the subungual finger. We present the case of a 77-year-old female with a chief complaint of a painful mass in her ulnar wrist. The differential diagnosis at the time was broad. Following a detailed history and physical exam, the etiology was believed to be that of a peripheral nerve sheath tumor. The patient was taken to the operating room for resection and biopsy of the mass. Histological evaluation confirmed that the mass was a glomus tumor. Our patient's symptoms had completely resolved and functional status had improved to baseline by the time of her two-week postoperative clinic visit. This case report demonstrates the many complexities in the diagnosis of a glomus tumor and the important role of surgical treatment in obtaining relief from extradigital glomus tumors.
