Unusual Glomus Tumor of Thigh: A Case Report

Seldom do glomus tumors (GTs) arise in other places of the body; they are mainly located on the nail beds of the fingers. We describe the case of a 34-year-old woman who presented with a 10-year history of occasional dull aching pain and swelling in her left upper thigh. A painful mass on the outside of the left upper thigh that was unrelated to erythema and edema was discovered during a physical examination. Following a magnetic resonance imaging assessment, the GT was diagnosed histopathologically and was surgically removed. The patient said that the pain had subsided and that their postoperative recuperation had gone smoothly. Because the symptoms are unclear, tumors in these locations are often misdiagnosed. After a thorough analysis of the literature, it was discovered that GTs of the thigh had a long period of symptomatic disease before an accurate diagnosis was made. This study highlights the unusual location of the GT, and its impact on the patients, and reviews relevant academic literature.
