Overview
Chondrosarcoma may be classified based on histological findings and location.
Classification
- Chondrosarcoma be classified based on histological findings and location.
Histological Classification
- Chondrosarcoma may be classified based on histological findings into following groups:[1][2]
Primary Chondrosarcoma
- Chondrosarcoma that arises denovo and comprises of following subtypes:
- Conventional chondrosarcoma - Low-grade, high-grade, and dedifferentiated chondrosarcoma (90% of all chondrosarcomas)
- Clear cell chondrosarcoma (1% of all chondrosarcomas)
- Mesenchymal chondrosarcoma (2% of all chondrosarcomas)
Secondary Chondrosarcoma
- Chondrosarcoma that arises from benign cartilage lesions includes (7% of all chondrosarcomas):
- Osteochondroma (<1% risk of malignant transfomation)
- Multiple hereditary exostosis (1-10% risk of malignant transformation)
- Enchondromas (1% risk of malignant transformation)
- Ollier's disease (25-40% risk of malignant transformation)
- Maffucci's disease(100% risk of malignant transformation)
Based on Location
- Chondrosarcoma may be classified based on location into following groups:[3][4]
- Centrally located within the medullary cavity. (central chondrosarcoma) (70% of all chondrosarcomas)
- Peripherally located on the surface of bone as a result of malignant transformation within the cartilaginous cap. (Peripheral chondrosarcoma) (15% of all chondrosarcomas)
