Abstract
The effectiveness of FN AC in both benign and malignant thyroid lesions was assessed in relation to histopathology. The study was carried out on 183 patients who were later subjected to thyroid surgery. Thyroid specimens were available for histopathologic examination in all these cases. On the basis of FN AC, 160 patients were found to have benign thyroid lesions where as 23 cases had thyroid malignancy. Colloid goitre and colloid goitre with hyperplastic foci comprised about 84.3% of cases. Papillary and follicular malignancies of thyroid formed 56.5% and 34.7% respectively. Histopathologically, 151 cases were found to be benign whereas 32 cases were malignant. Only 9 cases were wrongly diagnosed as having benign lesions by FNAC. All cases diagnosed by FNAC as malignant lesions were later confirmed by histopathologic examination. The accuracy of FNAC in diagnosing malignant thyroid lesion was found to be 95% in our study.
