Abstract:
Clear-cell chondrosarcoma, a recently specified entity, is a low-grade malignant tumor and has characteristic clinical, roentgenographic and pathologic findings which separate it from conventional chondrosarcoma and other benign tumors. Therefore, correct diagnosis is important from the viewpoint of both prognosis and therapeutic approach. We report a case of typical recurrent clear-cell chordirosarcoma. Typical round cells with clear cytoplasm, large nuclei, and small nucleoli were wellnoted. The clear cytoplasm was faintly positive in PAS staining. Electronmicroscopic study showed that these cells were of chondroid origin, showing indented nuclei, large dilated endoplasmic reticulum cisternae, bundles of actin-like filaments and a few glycogen particles.
