c category-26 aspirates (4.29% of total cases) were categorized as inadequate for evaluation or nondiagnosticGroup 2: Benign lesions included colloid goiter (57.07%, n = 331), colloid cyst (10.34%, n = 60), lymphocytic thyroiditis (7.93%, n = 46), adenomatous goiter/hyperplastic nodule (3.96%, n = 23), thyroglossal cyst (3.27%, n = 19), Hashimoto thyroiditis (2.59%, n = 15), and granulomatous thyroiditis (1.21%, n = 7)Group 3: AUS/atypical follicular lesion of undetermined significance (AFLUS) -- Two cases (0.34%) of hyperplastic nodule/FN with papillary hyperplasia, two cases (0.34%) of multinodular goiter/FN and one case of lymphocytic thyroiditis with hurthle cell change were diagnosed in this categoryGroup 4: FN/SFN -- There were 55 (9.48%) such cases; Out of which 40 cases (6.89%) were cytologically diagnosed as FN, 13 cases (2.24%) as adenomatous goiter, and two cases (0.34%) as hyperplastic noduleGroup 5: SM -- included seven cases; five cases of papillary carcinoma (including a case of follicular variant of papillary carcinoma), one case of FN, and one case of medullary carcinoma/oncocytic neoplasmGroup 6: Malignant -- There were 12 cytologically diagnosed malignancies; eight cases of papillary carcinoma, two cases each of anaplastic carcinoma, and medullary carcinoma.

Out of total 606 cases, histopathology was available in 171 cases. Among 171 patients who underwent surgery, 87.72% (150) were having benign, and 12.28% (21) were having malignant lesion. Figures [1](#F1){ref-type="fig"} and [2](#F2){ref-type="fig"} show gross and microscopic photographs of various thyroid lesions. In the present study, most common benign lesion (*n* = 64) on histopathology was goiter including colloid cyst, simple colloid goiter, nodular goiter and multinodular goiter; followed by goiter with secondary change (*n* = 51) and then follicular adenoma (*n* = 12). Out of 21 malignant lesions, ten (48%) were follicular carcinoma being the most common one, followed by six cases of papillary carcinoma (28%), four cases of medulla
