Periosteal chondroma of the clavicle: case report and review of the literature

Abstract

Periosteal chondromas (juxtacortical chondromas), are slow growing, rare cartilaginous lesion that arises adjacent to the cortex beneath the periosteum. They occur more in males in their 20s. We report a rare case of periosteal chondroma arising from the left clavicle of a 56 year old male. We could only find one reported case in the English literature of periosteal chondroma arising from the research and to the best of our knowledge, this is the second reported case.
