The authors present a case ofperiosteal chondroma of the proximal humerus. A 14-year-old girl was admitted with a painless mass around her left shoulder On magnetic resonance images, a subcutaneous lesion with hypointensity on TI-weighted images and marked hyperintensity on T2-weighted images, eroded the underlying cortical bone of the proximal humerus. The patient underwent marginal excision. There was no recurrence of the lesion during 3 years of follow-up.
