Intraneural glomus tumor within the digital nerve: a case report

Abstract

A glomus tumor is a soft tissue tumor that arises from the glomus body, a peripheral organ responsible for regulating skin temperature. It accounts for about 1% to 5% of tumors occurring in the hand, is mainly located in the subungual region, and is less than 1 cm in size. The diagnosis is mainly based on clinical symptoms, and the main symptoms are pain at the site of the glomus tumor, pinpoint tenderness, and cold intolerance. The pain is severe and usually requires surgical resection, and the results of complete resection of the tumor are good. This case report presents a 37-year-old female patient who developed pain in the radial side around the proximal interphalangeal joint of the right second finger without any traumatic history. On physical examination and imaging, a glomus tumor of the digital nerve was diagnosed and resected. After surgery, the symptoms improved and there was no recurrence. A careful examination and accurate diagnosis and treatment are necessary for symptomatic masses.
