Extra-Subungual Glomus Tumor

Two Case Reports

Abstract

Glomus tumors which usually arise in the subunguis may be difficult to diagnose when they occur in unusual locations. We report two cases of glomus tumor in the extra-subunguis. One arised in the subcutaneous of the left proximal knee and the other arised in the left great toe. Magnetic Resonance Imaging of both two cases disclosed a low intensity signal on T1-weighted images and a high intensity signal on T2-weighted images. Both tumors were completely excised. We believe that MR imaging is useful for the preoperative evaluation of soft tissue tumors of these regions.
