Background & Objective: Thyroid nodules are common clinical occurrence . More than 50% of the world ‘s
population harbours at least 1 thyroid nodule and the frequency of nodular thyroid diseases increases with age . It is
therefore no surprise that thyroid fine needle aspiration cytology (FNAC) is one of the most commonly practiced
areas in non gynaecologic cytopathology. Objective is to study cytopathology of various Thyroid lesions to
Differentiate and classify them according to the Bethesda System. To determine accuracy of the Bethesda
classification system for reporting. Methodology: This study was conducted in department of pathology BRIMS Bidar ,
around 100 thyroid FNAC reported cases retrospectively. Hand E , Geimsa and Pap stains were used. All smears were
screened and cytomorphological features were ascertained the diagnostic categories according to Bethesda System
for reporting thyroid cytopathology . In our study the age group were from 15 to 80 yrs and female prepondence was
reported . Non diagnostic (N D)confined 5 cases, Benign category were diagnosed in 75 cases, Atypia of
Undetermined Significance ( AUS) was diagnosed in 3 cases, Suspicious for Follicular Neoplasm (SFN) in 4 cases ,
Suspicious for malignancy ( SFM )in 4 cases and Malignant 9 cases. Results & Conclusion: A definite morphological
diagnosis can be made on FNAC which annuls the need of diagnostic biopsies . Surgery can be avoided in benign
lesions diagnosed on FNAC. TBSRTC has an excellent diagnostic specificity and accuracy in evaluation of thyroid
nodules. [Para R NJIRM 2016; 7(3): 52 - 54 ]
