Painful subcutaneous nodule of the arm. Extradigital glomus tumor (subcutaneous glomus tumor of the arm).

摘要

A 55-year-old man presented with a 2-year history of progressive pain in the right arm, which persisted at night and was exacerbated by exposure to cold. His past medical history was relevant for type 1 diabetes mellitus and hypertension. There was no history of cancer or prior trauma. Physical examination revealed exquisite point tenderness upon palpation of a 5-mm subcutaneous nodule located on the lateral aspect of the right arm, approximately 10 cm distal to the greater tuberosity of humer-us. No overlying epidermal abnormality was noted. The axillary lymph nodes felt normal.
