[Clear cell chondrosarcoma].

Two clear-cell chondrosarcomas localized in the proximal part of femur of a 46 years old man and a 36 year old woman had a lobular pattern and consisted of clear oval and polygonal cells with abundant glycogen. Many giant multinuclear osteoclast-like cells belonged to the tumour in which they were irregularly distributed. The ground substance was a little basophilic and chondroid in appearance. Electron microscopy confirmed the tumour chondroid character with atypical cells.
