The cases of forty-six patients who had dedifferentiated chondrosarcoma were reviewed. Two groups were identified: one in which a low-grade malignant chondrosarcoma was the precursor lesion and one in which a moderate to high-grade malignant chondrosarcoma was the precursor lesion. The radiographic features of these lesions ranged from that of a cartilaginous lesion that appeared to be benign to that of a destructive osteolytic tumor in which the cartilaginous component was overshadowed by the dedifferentiated component. Only three of the forty-six patients survived for more than two years. Resection alone, even when it was wide or radical, was not successful in controlling this lethal sarcoma.

Abstract
The cases of forty-six patients who had dedifferentiated chondrosarcoma were reviewed. Two groups were identified: one in which a low-grade malignant chondrosarcoma was the precursor lesion and one in which a moderate to high-grade malignant chondrosarcoma was the precursor lesion. The radiographic features of these lesions ranged from that of a cartilaginous lesion that appeared to be benign to that of a destructive osteolytic tumor in which the cartilaginous component was overshadowed by the dedifferentiated component. Only three of the forty-six patients survived for more than two years. Resection alone, even when it was wide or radical, was not successful in controlling this lethal sarcoma.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
