Abstract

Background: Thyroid lesions are most common head and neck lesions and a study was conducted to analyze thyroid aspiration smears by using The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC), it has standardized reporting and cytological criteria in thyroid aspiration smears.
Aims and Objectives: To analyze the thyroid aspiration cytology smears by using TBSRTC and categorize, subcategorize thyroid lesions according to the TBSRTC monograph and to correlate cytopathology and histopathology, wherever surgery was performed.
Material and Methods: The retrospective study of 390 patients who presented with various thyroid presentations. FNAC was performed, smears were stained and evaluation of smears and categorisation was done as per TBSRTC into non diagnostic/unsatisfactory (ND/UNS), Benign Atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS), Follicular neoplasms / suspicious of follicular neoplasms (FN /SFN), Suspicious of malignancy(SFM), and Malignant. Cytohisto correlation was done.
Results: Out of 390 thyroid FNAC’s ND/UNS 14(3.5%), Benign 357(91.3%), AUS/FLUS 01 (0.23%), FN /SFN08 (2.05%), SFM04(1.02%), Malignant 06 (1.53%). Cytohisto correlation was done in 53 patients sensitivity, specificity were calculated.
Conclusion: TBSRTC is an excellent reporting system for thyroid which avoids the unnecessary surgeries for the benign thyroids and gives proper guidelines to the clinicians about the patient management.

Keywords: TBSRTC, (ND /UNS), Benign, (AUS/FLUS), (FN /SFN), (SFM), Malignant.
