Chondrosarcoma: clear-cell variant. A report of sixteen cases
KK Unni, DC Dahlin, JW Beabout and FH Sim
Of sixteen adult patients with clear-cell chondrosarcoma, ten were men. The
tumor usually involved the proximal part of the femur or humerus.
Roentgenographically, the lesion was usually well defined and
indistinguishable from chondroblastoma. Serial roentgenograms occasionally
showed malignant progression of the lesion. Histologically, benign giant
cells and cells with clear cytoplasm were always present, and areas of
conventional chondrosarcoma were seen in about half the cases. Excision
usually resulted in recurrence; resection seemed to be curative. Four of
the sixteen patients died as a result of the tumor. Clear-cell
chondrosarcoma should be distinguished from chondroblastoma and treated
more aggressively.
