Fine needle aspiration cytology (FNAC) in malignant bone tumours.

Patients with malignant bone tumours often come at a very late stage of disease to Medical Colleges. Because of their high mortality rate, accurate & quick diagnosis of these lesions become essential, inspite of clinical, radiological and histopathological assessments. A simple, inexpensive, safe & least traumatic technique-fine needle aspiration cytology (FNAC) in diagnosis of 55 malignant bone tumours was carried out. Specific tumour types metastatic tumour (12), Giant cell tumour (12), Ewing's sarcoma (10), Osteosarcoma (7), Multiple myeloma (7), Chordoma (3), Chondrosarcoma (3) and Fibrosarcoma (1) could be ascertained in 87.2% whereas malignant tumour was suggested in 94.5% (52 cases).
