Tumeur glomique de l’index: à propos d’un cas

Abstract

Glomus tumor is a benign tumor that develops from the neuromyoarterial glomus of dermo-epidermal tissue. Its typical location is the distal phalanx of the fingers. We report a case of a glomic tumour in a 42 year old patient having pain at the level of the ulnar side of the distal phalanx of the right index finger since 7 months. Pain was triggered by applying pressure to the finger and by cold exposure. Clinical examination showed a painful point at the ulnar side of the right index finger by exquisite pressure and a positive Hildeth test. Standard finger radiograph objectified a small rounded subungual notch, completed by a MRI which showed a small 2 mm lesion of the nail matrix of the right index finger, evoking a glomus tumor (A). The patient underwent biopsy excision of the tumor (B, C, D, E, F); anatomopathological results revealed the presence of a glomus tumor. Clinical outcome was favorable with disappearance of pain .
