Clear cell chondrosarcoma of bone. A report of 8 cases.

We report 8 cases of clear cell chondrosarcoma from 350 cases of chondrosarcoma (2.2%) seen at Istituto Rizzoli. The lesion is always low grade in nature and occurs in an epiphyseal location, usually in the proximal femur or humerus. This relatively inaccessible location may hinder the exact diagnosis. Wide resection is the treatment of choice, although 3 of our patients underwent intralesional or marginal procedures. At present all patients are free of disease. However, a longer followup is essential because of the slow-growing nature of this sarcoma.
