Glomus Tumor in the Elbow: A Case Report and Review of Histopathological Findings

Abstract

Glomus bodies are neuromyoarterial apparatuses of the skin, implicated in body temperature control, and may undergo transformation with unregulated hyperplasia of their smooth muscle component. Glomus tumors most commonly occur in the subungual region of the fingers. These benign tumors are rare and constitute 1-5% of soft tissue tumors of the hand and may present as solitary or multiple masses. Solitary glomus tumors present with a classic triad of localized tenderness, severe pain, and cold sensitivity. We report a rare case of glomus tumor in the elbow and a review of the histopathological findings.
