Chondrosarcoma

Chondrosarcoma is the second common malignant bone tumor, only less than osteosarcoma, the more complex type. The majority of chondrosarcoma secondary to benign cartilage tumors, such as endogenous chondroma and osteochondroma. Tumor tissue is the basic development of complete cartilage, bone-like tissue without tumor. Directly from the sarcoma of the cartilage cells to form cartilage, often accompanied by calcification, ossification and mucinous change.

Chondrosarcoma occurred in malignant bone tumors of chondrocytes. Chondrosarcoma is endogenous cartilage ossification, but no real summary of osteoid tissue tumor. Chondrosarcoma can be divided into primary chondrosarcoma and secondary chondrosarcoma (original malignant enchondroma); according to the site can be divided into: central chondrosarcoma, borderline chondrosarcoma, bone Juxtacortical chondrosarcoma; according to the degree of cell differentiation can be divided into low, moderate, highly malignant chondroblastoma; according to histological characteristics of cells can be classified into general chondrosarcoma, clear cell chondrosarcoma, mesenchymal cells, such as chondrosarcoma.

General Chondrosarcoma, including a general primary or secondary, and occurred in the malignant intramedullary chondrosarcoma, as well as occurring in the periosteal bone surface chondrosarcoma.
