Abstract: The authors studied retrospectively 130 patients with thyroid tumors comparing the histopathologic diagnoses with fine needle aspirate (FNA) and frozen section results. FNA was performed in 118 patients with the following results: 75 (63.6%) benign, 21 (17.8%) malignant and 22 (18.6%) not conclusives. In seven cases false-negative result was obtained and there were six false-positive. These data reveals some drawbacks of this procedure. These results indicated that frozen as well as FNA are useful diagnostic procedure in helping to choose the most appropriate therapy in patients with thyroid tumors. On the other hand, traditional methods seems to be also important methods, such as scintilography, in the evaluation of thyroid diseases.
