[Clear-cell chondrosarcoma of bone]

Clinico-roentgeno-morphological characteristics of clear-cell chondrosarcoma are presented. Tumour cells had an abundant clear cytoplasm limited by a well discernible membrane; there were few giant multinuclear cells of the osteoclast type, zones of secondary osteogenesis and calcification. The lobulation of the structure was much less pronounced and the lobules were smaller and no so distinct as compared to an ordinary chondrosarcoma. All patients survived without recurrences and metastases after the operation.
