Three cases are reported of clear cell chondrosarcoma arising from unusual sites: talus, rib and vertebra. Radio‐graphically, two tumors showed osteolytic features and the vertebral tumor showed osteoplastic change. Histologically, ell tumors consisted of clear cells that had a centrally piaced nucleus surrounded by clear cytoplasm, osteoclast‐like giant cells, am of conventional chondrosarcoma, and various amounts of reactive bone. The tumor in the talus was initially diagnosed as benign chondroblastoma, but it recurred. The rib tumor showed marked cystic formation stimulating aneurysmal bone cyst. The osteoplastic radio‐graphic feature in vertebral tumor was considered to be due to the abundant bone formation.
