The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has put an effort to overcome personalized usage of descriptive terminologies in thyroid aspiration smears. Aims: The objective of this study was to interpret thyroid cytology by TBSRTC, to look for distribution of diagnostic categories and subcategories and to correlate the cytopathology with histopathology. Material and Method: This was 11 years retrospective study of 114 fine needle aspirations (FNA) of thyroid swelling. Results: An overall sensitivity of 80%, specificity of 91.86%, positive predictive valve of 92.85%, negative predictive valve of 97.46%, and efficiency of the study was 91.22%.
