Introduction: Fine-needle aspiration is well established and the best test in the primary diagnosis of disorders of Thyroid with a high accuracy. A uniform reporting system for thyroid FNA will facilitate effective communication among all health professionals. 

Aims and Objectives: The aim of the study is to provide consistent diagnostic terminology by using new reporting system – Bethesda system. Cytopathology to histopathology correlation help us to calculate the malignancy risk rates of the different BSRTC categories at each individual institution.

Material and Methods: The evaluation begins with demographic factors, physical examination, appropriate investigations, cytological, histopathological correlation and calculating malignancy risk for each category. 1,057 patients of all ages and sexes with clinical diagnosis of goitre in teritiary health care centre were studied.

Results: Out of 1,057 patients, 931 were female and 126 were male patients. Fnac was done in all 1,057 cases and classified the lesions on FNAC using standard system of Bethesda. Out of 1,057 cases, 35 cases were diagnosed as Non Diagnostic/Unsatisfactory, 906 cases as Benign, 57 case as Atypia of undetermined significance/atypical follicular lesion of undetermined significance, 29 as follicular neoplasm/suspicious of follicular neoplasm/ Hurthle cell neoplasm/suspicious of Hurthle cell neoplasm, 11 as suspicious of malignancy and 19 as Malignancy. Out of 1,057 patients, 130 were undergone different modalities of surgical treatment. On histpathology examination out of 130 cases, 43 were Multinodular goitre, 06 were colloid goitre/Colloid cyst, 09 were Hashimotos thyroiditis, 21 were Adenomatoid Goitre, 21 were FollicularAdenoma, 1 was hurthle cell adenoma, 3 were Follicular Carcinoma, 2 were Hurthle cell neoplasm, 17 were Papillary Carcinoma, 3 were Follicular variant of Papillary carcinoma and 4 were Micropapillary carcinoma.

Conclusion: Standard reporting system will help to reduce different diagnostic schema used by different institutions.
