Knee glomangioma: a rare location for a glomus tumor

Abstract

Glomus tumor is a rare, benign neoplasm rising from the glomus apparatus of the skin. It occurs most frequently on fingers and toes and accounts for 1.6% of all soft tissue tumors. Clinical diagnosis may prove difficult if the tumor occurs on an extra digital location. We report a case of a vascular-type glomus tumor(glomangioma) found in an atypical location,namely the lateral aspect of the knee joint.
