Fine Needle Aspiration Cytology of Thyroid Lesions: Diagnostic Accuracy and Limitations
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 8
Abstract
Fine Needle Aspiration cytology (FNAC) of thyroid gland is firmly established as an important test for the evaluation of thyroid disease and an effective test for the preoperative diagnosis of solitary thyroid nodule. This study was undertaken to determine the correlation between the FNAC and histopathologic diagnosis of the thyroid lesions. Total 179 cases were included in this study. All had FNAC thyroid.Out of the total 179 patients studied, 123 were cases of benign thyroid lesions,14 were malignant, 3 were inadequate, and 39 were follicular neoplasm. Histopathology of 48 thyroid specimens showed 17 colloid and nodular goiter,3 colloid cyst,1 thyroglossal duct cyst, 1 Hashimoto’s thyroiditis,1 granulomatous thyroiditis, 11 Follicular adenoma,1 hurthle cell adenoma, 7 Papillary carcinoma and 4 Follicular carcinomas and 2 cases turned out to be false negative.By comparing the results of FNAC and histopathology, FNAC has sensitivity of 84.61% and specificity of 100% and an accuracy of 95.83% in the diagnosis of malignant thyroid diseases. FNAC is safe, inexpensive and less invasive diagnostic method with excellent patient compliance. Its existence use can make the management of thyroid swelling cost effective to avoid unnecessary surgery on conditions like thyroiditis.
