The thyroid fine-needle aspiration (FNA) is the decisive examination in the preoperative diagnostics of thyroid nodules. Different cytohistologic studies have revealed that the accuracy of FNA for thyroid nodules varied from 69% to 94%. The aim of our study was to compare the results of FNA with regard to final histopathological diagnosis among patients with follicular tumor, Hurthle cell tumor or papillary carcinoma in FNA. We retrospectively analyzed medical documentation of 51 patients (mean age 57.9 years, 49 women and 2 men) from the Endocrinology Department from 1997 to 2002 years. Based on FNA 29 patients were diagnosed as having follicular tumor, 10 as having Hurthle cell tumor and 12 as having papillary carcinoma. Carcinoma was detected histopathologically in 38% of patients with follicular tumor. Follicular carcinoma was detected histopathologically in 10% of patients with Hurthle cell tumor. Cytological diagnosis was confirmed histopathologically in 66.8% of all patients with papillary carcinoma in FNA. In accordance with our results the confirmation of malignant neoplasm can be expected in more than 80% of cases with papillary carcinoma in cytological examination. In case of follicular or Hurthle cell tumors the frequency of malignant neoplasm was less than 40% and 10% respectively.
