A sixteen-year-old boy presented to the orthopaedic service with right shoulder pain and a shoulder mass. Physical examination revealed a well-developed adolescent boy with a prominent mass in the proximal aspect of the right humerus. The mass was tender to palpation, and the right shoulder had a decreased range of motion due to pain. No neurovascular abnormalities were found. A plain radiograph was made, and a magnetic resonance imaging scan was acquired.
