Role of Fnac in diagnosis of thyroid lesions

Abstract

Aims and Objectives: The aim of this study is to determine the role of FNAC in diagnosing thyroid lesions with the use of Bethesda system. Materials and Methods: A total of 130 FNAC cases of thyroid lesions were studied over a period of 1 year from June 2017 to June 2018. Results: Bethesda system was used to classify the thyroid lesions, out of which 4.6% constituted the category Non diagnostic, 81.4% constituted the category Benign, 4% constituted the category Follicular neoplasm, 1.53% constituted the category Suspicious of Malignancy, 9.2% constituted the category Malignant and there were nil cases in the category Atypia of Undetermined significance. Conclusion: FNAC serves as a preliminary investigation in the diagnosis of thyroid lesions and application of Bethesda system helps in precise cytological diagnosis. FNAC serves as a safer, inexpensive and as a first line of investigation in diagnosis of thyroid lesions though after having understood its limitations.
