Our classical and unusual chondroid tumors of bone were reviewed as follows: 31 cases of solitary osteochondroma, 13 cases of chondrosarcoma, 6 cases of multiple osteochondroma, each 5 cases of solitary and multiple enchondroma, each 2 cases of benign chondroblastoma and mesenchymal chondrosarcoma, and one case of chondromyxoid fibroma.The clinical, roentgenologic, and pathologic aspects of these tumors have been discussed. We classified four histological patterns for tumorous chondroid tissue: mesenchymal, myxomatous, chondroblastic, and cartilaginous. It is true that one or more manifestations of these histological patterns may be found in each individual variation of chondroid tumors.It should be emphasized, that over five year survival rate of malignant chondroid tumors proved to be more excellent than of osteosarcomas and, as for the treatment, some more conservative and effective orthopedic procedures except amputation of the limb may be more expectedly in future.
