Introduction – Diagnosis of bone lesions is a multimodality approach. FNAC is simple cost effective outpatient procedure which can help in preliminary diagnosis of bone lesions. Objective – The aim of the study is to evaluate the role of FNAC in diagnosis of bone lesions and its diagnostic accuracy. Results –A prospective study of 44 cases of clinicoradiologically suspected bone lesions was done. Cytology revealed benign bone tumors in 19 patients (51%), malignant bone tumors in 13 patients (35%) and non neoplastic bone lesions 5 patients (5%). Among the malignant bone lesions primary bone lesions comprised 19% and metastatic bone lesions comprised 16%. The most common type of bone tumours encountered was giant cell tumours (29.73%) followed by metastatic tumours (16.22%) and osteosarcoma (10.81%). The overall accuracy rate of FNAC was 81.08%, sensitivity 84.6%, specificity 79.17%, positive predictive value 68.75% and negative predictive value 90.47%. Conclusion – FNAC along with clinical and radiological findings has a high diagnostic accuracy which can help the clinician in preoperative diagnosis.
