Intraosseous glomus tumor in the ulna. A case report.

Glomus tumors are benign vascular tumors composed of round to oval uniform cells associated with vascular structures, usually found in the soft tissue of the nail bend. A 24-year-old woman with a two-year history of progressive right elbow pain and swelling was found to have a histologically characteristic intraosseous glomus tumor in this unusual location. Excision was followed by complete relief of symptoms.
