Glomus Tumor Originating from a Digital Nerve.

Glomus tumors are relatively rare benign neoplasms that most commonly occur in the hand. They arise from the normal glomus body, which is an arteriovenous shunt related to thermoregulation. Glomus tumors in nerves are an extremely rare occurrence, as normal glomus bodies have not been found in nerves. We describe the case of a 30-year-old woman with a glomus tumor originating from a digital nerve that required excision along with a nerve segment. In this case, because the tumor was inseparable from both fascicles of the nerve, a segment of the ulnar digital nerve was resected with the tumor. After tumor resection, direct nerve repair was performed and the patient showed favorable outcomes.
