Abstract

Secondary chondrosarcoma is a distinctive type of tumor that arises from cartilage lesion. Frequently it has a connection with single or multiple osteochondromas. Some cases arise from other diseases, such as Maffucci Syndrome and Ollier’s disease. A sharp increase in the size of the «cartilaginous cap» osteochondromas is a sign of transformation into a secondary chondrosarcoma. However, there is no strict restriction on the thickness of the «cartilaginous cap», which can be considered pathognomonic malignancy. The overall survival rate for 5 years is approximately 90%. Surgical resection with wide margins is the best treatment option, but local recurrence remains a significant problem in about 10–20% of patients. Patients with secondary pelvic chondrosarcoma are particularly at risk of local recurrence.
