Figure 1. Antero-posterior (A) and latero-lateral (B) X-ray images of the right forearm and wrist demonstrate a lytic expansile lesion involving the distal epiphysis of the ulna, which is completely consumed. „The osteolytic features are so prevalent as to give the roentgen-ray picture of a tabula rasa„ . The lesion margins are irregular with an aggressive appearance and relatively broad zone of transition without sclerotic zones. There is no convincing periosteal reaction. No evidence of calcifications can be seen within the tumor stroma. The styloid of the radius, carpal bones, and bases of the metacarpal bones seem osteopenic; cortical bone is intact.
