Periosteal chondroma of the proximal radius: a case report

When a chondroma is localized in the superficial region of the bone it is defined periosteal or juxtacortical chondroma. This is a rare and benign cartilaginous lesion that more frequently affects males, and is generally observed in the tubular bones of the hand; it may, however, affect the other major bones, particularly the proximal end of the humerus. Age of onset is the second or third decade of life. Symptoms include moderate local pain. The clinical case presented here has two special features: the first is the site; based on an analysis of the international literature it seems that an analogous lesion at the level of the radial neck has not as yet been described; the second is the symptomatology that brought the patient to our attention.
