Abstract

Introduction: Thyroid lesions are of great importance because most are amenable to Medical or Surgical management. The Medical diagnosis of Thyroid lesions is crucial as Malignancy necessitates Surgery while follow-up is important just in case of Benign lesions. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was introduced in 2007 to standardize terminology utilized in reporting thyroid cytology.
Material and Methods: A retrospective observational study of already diagnosed cases of Thyroid in FNAC was performed in the Department of Pathology at Late BRKM Medical College, Bastar over a three years period from January 2017 to December 2019. The FNAC smears were reclassified according to the 6 diagnostic categories of TBSRTC.We could pursue follow up Histology for 160 cases. The diagnosis offered in FNAC was compared with that observed on Histopathological examination.
Results: On cytology out of 386 cases, 21(5.44%) categorized as Non-Diagnostic/ Unsatisfactory Samples, 338 (87.56%) cases as Benign Follicular Nodule, And 10 (2.59%) as Atypia of Undetermined Significance/Atypical Follicular Lesion of Undetermined Significance (AUS/AFLUS), 3 (0.78%) as Follicular Neoplasm/Suspected Follicular Neoplasm (FN/SFN), 4 (1.04%) as Suspicious For Malignancy, and 10 Cases (2.59%) as Malignant. Histopathological follow-up of 160 cases. The malignancy rate for the Non-Diagnostic category was 0%, Benign category was 1.44%, AUS/FLUS category was 33.33%, FN/SFN category was 50%. Suspicious for Malignancy category was 66.66%, malignant category was 100%.
Conclusion: The Bethesda system is the most suitable reporting system for cytopathology of Thyroid lesions. It minimizes the surgical procedure for benign lesions.
