[Glomus tumor of the extremities].
Glomus tumor is a neuro-myo-arterial benign tumor accounting for 1 to 5% of hand tumors which occurs principally in young adult females. It may be unique or multiple. Acute, focalized, pain is the main sign, the pressure of a small trigger zone induces a syncopal pain and immediate hand withdrawal. Differential diagnoses includes neurinoma, melanoma, hematoma, osteoid osteoma, fibrokeratoma, mucoid cyst, angioma, and exostosis. The diagnosis is suspected on clinical grounds, and X rays exhibits a bone erosion in one third of the cases. Magnetic resonance angiography is now the first line non invasive tool for both diagnosis and precise localization. Treatment consists in complete surgical tumor resection (J Mal Vasc 1999; 24: 364-367).
