A study of fine needle aspiration cytology findings with thyroid function test, anti-thyroid antibody, and clinical pathological parameters in cases of chronic lymphocytic thyroiditis

: Chronic lymphocytic thyroiditis is autoimmune thyroiditis; it considered as second most common thyroid disorder diagnosed on FNAC following colloid goitre. a reliable and efficient method for diagnosing these lesions. Lymphocytic frequently affects women, primarily compared to men commonly found with hypothyroidism, euthyroidism or every so often hyperthyroidism. The incidence rate of Hashimoto’s 1–4%, an occurrence 30–60/100000 population per year. Autoimmune can be categorised the cytomorphological features FNAC. To compare cytological findings TFT in thyroiditis. One hundred ten patients swellings were presented examination, serology Anti TPO antibodies Ultrasonography during 2020–2021. In addition, fine needle aspiration cytology was performed using non-aspiration techniques. Anti- Avion CLX 120 auto analyser based Chemiluminescence method. Out 110 cases midline neck swelling our department, Thyroiditis observed 43 cases. affected age group 21–30 years, male: female ratio being 1:3. Most diffuse few nodular swelling. Grading done by criteria used Bhatia et al Anti-TPO antibody elevated 19 (26.2%), TSH 28 (40.81%). These cytology, clinically also correlating radiological findings. Grade 3 lymphoid infiltrate seen 53.33% (16/30) cases, 2, eight (62.50%). 1 five (11.63%). Among (65.12%) show 7 (16.28%) hyper, 8 (18.60%) Euthyroidism. 26 showed ultrasonography, solitary nodule. infiltration statistically correlates anti-TPO conjunction ultrasonography enlargement gland. presence Hurthle cell change, giant cells, anisonucleosus, granulomas do not find any statistical correlation are corresponding 2. Through this study, we conclude that remains gold standard despite having different diagnostic modalities accessible Smears depends follicles, along positivity antithyroid (anti-TPO antibody) TSH. firmly associated Thyroiditis.
