Introduction- Chronic thyroiditis embraces a heterogenous group of thyroiditis. Hashimoto’s thyroiditis forms the largest and clinically most significant cause of chronic thyroiditis. FNAC of thyroid provides a safe and accurate method of diagnosis of this condition. As there is paucity of literature on Hashimoto’s thyroiditis and the input of patients presenting with features of Hashimoto’s thyroiditis is on the rise, this study is under taken to correlate the cytomorphological features of Hashimoto’s thyroiditis

with clinical, biochemical and with antithyroid antibodies where ever feasible.

Objectives

1. Analysis of cytomorphological features on FNAC in Hashimito’s thyroiditis.

2. To determine the correlation between various cytomorphological features and biochemical & serological parameters in cases diagnosed as HT.

3. To correlate cytological diagnosis with histopathology wherever possible.

Materials and Methods This prospective study was conducted on 100 patients attending the cytopathology department of Adichunchanagiri Institute Of Medical Sciences, B.G. Nagara. Cytologically proven, cases of Hashimoto’s thyroiditis over a period of two years, from November 2017 to May 2019 formed the study material. The various parameters like patients clinical presentation, antithyroid antibodies & hormonal profiles, were studied. Fine needle aspiration of thyroid gland and grading of thyroiditis was done on smears. The grades were correlated with above parameters and the correlation indices were evaluated statistically. RESULTS: Most of the patients were females (97%) who presented with a diffuse goiter (91.%). Hypothyroid features were present in 62.7% of cases. Anti TPO antibody showed positivity in.93.4% of patients. Cytomorphologic spectrum of Hashimoto’s thyroiditis was analysed and graded. Most of them had grade II disease by cytology.No correlation was observed between grades of cytomorphology and biochemical &

serologic parameters. Conclusion Despite the availability of several tests for diagnosis of Hashimoto’s thyroiditis, ‘FNAC’ remains the gold standard.
