title: [A rare location for extratruncular vascular malformation].
abstract: We report on an undefined tumor of the right ulnar side of the elbow in a 15-year-old boy. The clinical examination showed painful swelling in the area of the ulnar nerve at the right elbow as well as sensory and motor deficits of the right hand corresponding to distribution of the ulnar nerve. Ultrasound examination and magnetic resonance imaging showed a tumor along the nerve. Subsequent surgical therapy included tumor decompression by division of the fascia. The histological examination demonstrated a capillary hemangioma that infiltrated the ulnar nerve.After surgery, oral glucocorticoid therapy with cortisone (5 mg/kg per day) was administered over a period of 4 weeks, alternating between 1 week of therapy and 1 week without medication. The result of this combined therapy was a rapid diminution of the tumor and an almost complete restitution of the neural function.
