Letters to the Editor Diagnostic Aspiration Cytology of Sacral Chordoma Journal of Cytology 2007; 24 (1) : 60 To the Editor,

Chordoma is a rarely encountered slowly growing encapsulated malignant tumour of fetal notochord origin affecting axial skeleton, which mainly involves sacrum, base of skull and cervico-thoracic spine in decreasing frequency.1 On microscopy, the tumour shows varied but characteristic morphological features and a pre-operative fine needle aspiration biopsy (FNAB) examination of the tumour is diagnostic.2 Very few case reports are available of pre-operative cytological diagnosis of chordoma.3 We recently came across an unusual case of sacral mass where fine needle aspiration biopsy cytology along with radiological findings clinched the diagnosis of chordoma. A 70 year old female was admitted with th
