Introduction: FNA of musculosketal masses provides a number of advantages and disadvantages. However FNA of soft tissue and bone is not widely accepted to obtain a definitive diagnosis for tumours. This study aims to establish the diagnostic accuracy of fine needle aspiration cytology in diagnosing mesenchymal tumours with reference to the subsequent histopathology report.

Material and Methods: 634 patients were studied over a period of 2 years. A comparison was made between cytological and histological findings whenever possible. On correlation the sensitivity, specificity, accuracy and positive predictive value were calculated

Result: Out of 634 cases, 54.36% of benign mesenchymal and 62.5% of malignant mesenchymal tumours were seen in males. 45.63% of benign and 37.5 % of malignant mesesnchymal tumours were seen in females. Soft tissue tumours (91.95%) were found to be much more common as compared to bone tumours (8.05%). The Sensitivity, Specificity and diagnostic accuracy of FNA of malignant lesions was found to be 90%, 97.72% and 95.31% respectively.

Conclusion: The present study concluded that FNA is fairly reliable for correct preoperative diagnosis and management of mesenchymal tumours.
