The use of fine-needle aspiration (FNA) in the diagnostics of Hashimot's thyroiditis

Hashimot's thyroiditis (HT) may be clinically examinated by many methodes. Thoday fine-needle aspiration (FNA) is also necessary diagnostic procedure in analyzing. In the period of 2 years citologically was analyzed 600 aspirates stained with HE and MGG and 35 (5,8 %) were diagnosed as HT. Statistically was confirmed high significance of the sex and the ages for the genesis of HT (X-2=24,02; p,0,005). We analyzed correlation between clinical and cytological diagnosis: in 82 cases initial clinical diagnosis was "Thyroiditis", and among them 46 (56 %) were cytological confirmed. From 35 patients with FNA diagnosis HT in 23 cases (66 %) HT was suspected clinically. Several authors noted a high incidence of thyroid carcinoma in patients with HT. We researched association of HT and thyroid tumors, and we did not confirm that HT is premalignant lesion (X-2=1,22, p.0,05). HT and its association with other lesions could be clearly diagnosed with FNA, and we recommend FNA as a first line investigation in HT.
