The smears shows characteristic Physalliphorous cells in a metachromatic background of myxoid material entrapping cords of cuboidal cells. Differential diagnosis in cytology include conventional and myxoid chondrosarcoma, myxoid liposarcoma, myxoid malignant fibrous histiocytoma, metastatic mucinous carcinoma and myxo-papillary ependymoma. The distinguishing features between these neoplasms are discussed. Preoperative diagnosis of chordoma permits optimum planned surgery.
