| Two years later, Mr. Turner learned he had a type of cancer called chondrosarcoma in his right pelvis. |
| Of the different types of primary bone cancer, chondrosarcoma has the best prognosis and osteosarcoma the worst. |
| Extraskeletal cartilaginous lesions are extremely uncommon and include soft tissue chondroma, mesenchymal and extraskeletal myxoid chondrosarcoma. |
| An extremely rare form of chondrosarcoma also may occur as a primary tumour in soft tissues and muscle without involvement of the bone. |
| Enchondromas tend to be painless but are potential sources of a malignant cartilage-forming tumour called chondrosarcoma. |
| In our case, the patient was found to have a chondrosarcoma of the left maxilla with extension into the infratemporal fossa. |
