Evaluation of FNAC in Bone Lesions

ABSTRACT

The aim of the present study is to evaluate the utility of FNAC in diagnosing bone lesions especially bone tumours. Methods: A total of 120 cases were selected from patients attending OPD and admitted in IPD in MLB Medical College, Jhansi, presenting with complaints of swelling arising from bone. FNAC of the lesion was performed, with guidance of X-Ray reports when available, clinical details, history of present illness & other physical findings have also been noted, and considered while making the diagnosis, and the findings were compared with that of histolgical specimen whenever available. Results: The present study includes 355 malignant cases, of which 53.8% are primary neoplasms, 7.6% are metastatic lesions, and 38.4% are locally malignant lesions. The most common primary bone malignancy in this study is Osteosarcoma. Comparison of Cytological and Histological Diagnosis in all cases was done. 39 malignant lesions were reported on Cytological basis and all 39 were found correct on histological correlation, while 18 out of total 21 benign lesions were diagnosed correctly, as confirmed by subsequent histological examination. Out of total 51 inflammatory lesions 42 were diagnosed correctly, 9 aspirations were found inadequate for reporting. Conclusion: Fine Needle Aspiration Cytology (FNAC) is a very valuable procedure in patients with bone lesions. The complications are almost nil, the cost is very low, is minimally painfull, is an OPD procedure and informative reports are available within 12-48 hours.
