[Optimalization of methodical repertoire for laboratory diagnostic of autoimune diseases of the thyroid gland--aspiration cytology versus histology (cytodiagnostic accuracy)].

In this study was evaluated the rate of cytodiagnostic accuracy of Hashimoto's thyroiditis (HT) in smears prepared from thyroid fine-needle aspirates in 72 cases and of focal lymphocytic thyroiditis (FLT) in 101 cases. The cytodiagnostic accuracy of Hashimoto's thyroiditis (HT) was 75% and 20% in case of focal lymphocytic thyroiditis (FLT). In case of focal lymphocytic thyroiditis (FLT) the cytodiagnostics of autoimmune lymphocytic diseases of thyroid gland apears to have very low ability.
