Giant cell tumor associated with trauma

Abstract

Presented is a case report of a 19-year-old man who developed a giant cell tumor in the distal ulna following trauma to the carpus. Roentgenograms and bone scan revealed a fracture of the scaphoid and no other bony abnormalities. On year later, after the scaphoid fracture had healed, the same investigations demonstrated a giant cell tumor of the distal ulna. Circumstantial evidence suggests a possible role for trauma in the pathogenesis of giant cell tumor.
