Abstract :

Back ground: The Bethesda system for reporting thyroid cytopathology (BSRTC) stratifies thyroid fine needle aspirations (FNAs) into 6 main diagnostic categories and conveys uniform language among pathologists and clinicians. It has standardized the diagnostic approach to cytomorphological criteria and reporting. Aim: To evaluate the results of FNAC in diagnosis of thyroid lesion using Bethesda system of reporting Materials and methods: We retrospectively revived one year thyroid FNAs and classified according to BSRTC. Results: Total 150 thyroid FNAs were reviewed and categorized into diagnostic categories of Bethesda system. Among those 72% belonged to benign category (Bethesda 2), followed by Non diagnostic (Bethesda 1), 13%, Malignant (Bethesda 6) 6%, Follicular neoplasm (Bethesda 4) 5% and both Suspicious for malignancy (Bethesda 5) and Atypia of undetermined significance (Bethesda 3) 2% each. Conclusion: Interpretation of thyroid FNA varies from one laboratory to another resulting in diagnostic ambiguity in few cases. Application of BSRTC may ing in objective guidelines for reporting thyroid cytopathology.
