Fine Needle Aspiration Cytology in the Management of Tumors and Tumor like Lesions of Bone

FNAC should be considered as the part of routine preliminary investigation of orthopaedic patients presenting with musculoskeletal tumorous lesions. A total of 110 cases were screened cytologically in the background of clinical, radiological findings and biochemical tests. Primary malignant tumor formed the major entity accounting for 56% of the cases, while benign tumors comprised 8% only. Overall success rate of needle aspiration cytology in diagnosing tumors and tumor like lesions was 92%. Giant cell tumors of bone was the most common malignant lesion observed in 15 cases (30%), followed by Ewing's Sarcoma in 5 cases (10%). Cytologic diagnosis was completely compatible with the final histopathologic diagnosis in 82.3% of cases.
