    Our study on 106 cases of bone tumors aims at correlating the clinical, radiological and cytological findings of benign and malignant tumors of bone and evaluating the usefulness of percutaneous biopsy as a diagnostic tool in underdeveloped countries. Giant cell lesions were the most common benign tumor, 42 cases (84%) and giant cell tumor was the most common giant cell lesion in our study, 27 (64.3%). Round cell tumor appeared to be the most common malignant tumor of bone, 20 cases (35.7%). Osteosarcoma represented 15 cases (14.2%) of all bone tumors and 26.8% of all malignant bone tumors in our study. Final histopathological diagnosis was available only in 54 cases. Out of which 53 cases showed concordance with previous cytological diagnosis. Only a single case of chondrosarcoma was misdiagnosed as chondroma on FNAC (false negative). The sensitivity and specificity of FNAC was 96.0% and 100% respectively while positive predictive value and negative predictive values were 100% and 96.7% respectively. The diagnostic accuracy in our study was 98.1%.
