Abstract

Swelling in thyroid are frequently encountered. Clinical evaluation helps in diagnosis but is difficult to distinguish the early malignant lesions from the more prevalent benign goiters. FNAC is a simple and safe procedure, carried out in OPD with minimum equipment and has good patient compliance. As FNAC is the primary investigation for the management of thyroid lesions, its interpretation is very crucial. This study aims at classifying the cytomorpholgical profile of nodular and diffuse thyromegaly cases with emphasis on Bethesda system of reporting. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is used for clarity of communication and recommends that each case should be reported in 1 of 6 diagnostic categories which include Category I –Non –diagnostic, Category II- Benign, Category IIIAtypia of undetermined significance / Follicular lesion of undetermined significance (AUS/FLUS), Category IV - Follicular neoplasm / Suspicious for follicular neoplasm (FN/SFN), Category V- Suspicious for malignancy (SFM), Category VI – Malignant, thus facilitating a uniform communication among the managing team of doctors and leaves no confusion regarding the management of thyroid lesions. A total of 300 cases with thyroid swellings were studied during the period of January 2013 to June 2014. FNAC of thyroid was done in all cases and the cytomorpholgy of the individual thyroid lesions were evaluated and all cases were reported using TBSRTC. Of the total 300 cases, 3 cases(1%) were reported in category I, 274 cases (91.3%) were reported in category II, 1 case(0.3%) in category III, 12 case (4%) in category IV , 2 cases (0.7%) in category V, 8 cases (2.7%) in category VI. Major bulk of cases were seen in category II. Thus the application of TBSRTC bridges the gap in communication between the clincians and helps in the proper patient management.
