Malignant cartilage tumors may arise de novo in bone or they may be superimposed on preexisting benign cartilage tumors. The former are classified as primary chondrosarcomas and the latter as secondary. Also, chondrosarcomas may arise peripherally or centrally with relation to the bone and some may even arise extraskeletally. The common histologic features are that all are composed of cells that can produce hyaline cartilage matrix and that there is a tendency toward lobulation. Cartilage matrix undergoes calcification in characteristic patterns, producing telltale radiologic signs which aid diagnosis. The roentgenogram in cartilage tumors is also useful in that it provides clues as to the aggressiveness of the lesion, based on its size, pattern of bone destruction, and reactive bone formation.
