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