A case of sacrococcygeal chordoma diagnosed by fine needle aspiration is presented. This is a case of a 54-year-old woman who came with coccygeal pain of 5-6 months duration. Aspiration biopsy cytology revealed many nests of cells having abundant bubbly cytoplasm and round to oval variably sized nuclei. The cells had indistinct cytoplasmic borders and many of the cells had cytoplasmic vacuoles. The nuclei had thin regular nuclear membranes, finely granular chromatin and one or two small nucleoli. The cells were generally monotonous, but focally pleomorphic with giant cell formation. Mitotic figures were scanty. The backgroud of the aspirate contained abundant mucinous materal. These findings were typical of those of recorded chordoma cases and the diagnosis was confirmed by a following open biopsy. The patient received 4,000 rads of neutron radiotherapy and has been well till March '88.
