Malignant transformation to chondrosarcoma is rare. We cite a case of SC of the hip refractory to arthroscopic debridement, found to have secondary chondrosarcoma on aborted total hip arthroplasty, in which curative treatment was ultimately obtained with external hemipelvectomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>SC has the potential to undergo malignant transformation to chondrosarcoma.
