Fine needle aspiration biopsy cytology of chondrosarcoma

Fine needle aspirates of ten chondrosarcomas were evaluated, and the cytologic features of this tumor were described. Some malignant cells in the smears of chondrosarcoma resembled cells of an epithelial origin and could be misinterpreted as carcinoma cells. The morphologic features described for chondrosarcoma should be helpful in avoiding such a diagnostic error.
