This paper describes 4 cases of secondary chondrosarcoma in hereditary multiple exostosis. The incidence of malignant change in hereditary multiple exostosis was estimated to be about 8.7%. These tumors arised from the pelvis and the proximal end of the femur. All of these tumors were giant but microscopic findings were those of well differentiated chondrosarcoma.
