Materials and Methods: We retrospectively analyzed the fine?needle aspiration (FNA) features of 52 HT patients.

Based on cytomorphologic features patients were categorized into three groups. Clinical findings including thyroid function and thyroid peroxidase (TPO) antibody profile were correlated with cytomorphologic features in all three groups. Results : Majority of the patients were females and in 2nd, 3rd and 4th decades. Diffuse goiter and thyroid hypofunction were the common findings. Significant number…
