چکیده

We present a case of osteosarcoma arising from an osteochondroma of the right tibia in a 71 year old man. Theradiographic studies were suggestive of a malignant lesion. Histologic examination showed a conventional osteosarcomathat eroded the cartilagenous cap. The patient received postoperative chemotherapy with no evidenceof metastasis until three years following the operation. The occurrence of osteosarcoma out of osteochondromais an extremely rare event and very few cases have been reported.
