Glomangioma of the Knee: A Case Report

Glomus tumors are rare, benign mesenchymal neoplasms arising from the glomus body, typically found in the digits and involved in thermoregulation. We present a 54‐year‐old male with a 5‐year history of sharp, throbbing anterior knee pain worsened by activity. Initial imaging showed only mild osteoarthritis without soft tissue abnormality. Persistent, localized symptoms prompted further evaluation, revealing a small subcutaneous mass anterior to the patellar tendon. Surgical excision yielded a well‐circumscribed ovoid lesion, confirmed as a glomangioma on histology. Following the procedure, the patient experienced complete and sustained symptom resolution. This case highlights the diagnostic challenges of extradigital glomus tumors and underscores the importance of early identification and surgical intervention to reduce patient morbidity.
