In this series six cases of papillary carcinoma on cytology, four were confirmed on histopathology, remaining two were nodular colloid goiter with cystic degeneration.
The other benign tumours encountered in the present study were extra gonadal mature teratoma, schwannoma, benign mesenchymal (BST) lesions like fibrohistiocytic lesion, solitary fibrous tumour (SFT), inflammatory pseudo tumour (IST) and colloid goiter one each.
FNA diagnosis of HT with colloid goiter was made in few cases (n = 5).
The commonest benign pathological lesion encountered was colloid goiter accounting for 60% of all thyroid lesions.
Limitation of thyroid FNAC we faced in this study is that: Since there is a group of lesions which overlap benign and malignant features, for instance, the distinction between a cellular colloid goiter and a follicular lesion was impossible so such cases had been excluded from the study [12,13].
The results in Table 2 show that 81.64% of the thyroid FNACs were cytologically benign and colloid goiter occupied 58.5%.
Following the clinical examination, our differential diagnoses were colloid goiter, branchial cyst, and thyroglossal duct cyst.
Of the 100 cases, 57% cases were colloid goiter, 9% lymphocytic thyroiditis, 4% Hashimoto's thyroiditis, 6% Graves' disease, 6% follicular neoplasm, and 2% papillary carcinoma.
The diagnosis of Hashimoto's thyroiditis was confirmed by finding lymphocytic infiltrates in clusters of follicular epithelial cell, Hurthle cell changes and increased number of lymphocytes in the background and of colloid goiter by the presence of cohesive monolayer sheets or poorly cohesive clusters of follicular epithelial cells, bare nuclei, macrophages and abundant colloid, multinucleated giant cells, epithelioid cell clusters and anisonucleosis.

Case 1: Cytological smears showed abundant colloid with moderate number of follicular cells arranged in sheets and occasional macrophages favoring the diagnosis of nodular colloid goiter. Histology of this case showed the presence of microscopic focus of papillary carcinoma 8 mm in diameter.
