Biopsies made in external centers were included inpreoperative FNAB results. FNAB results were examined according to Bethesda 2007 in 6 categories: unsatisfactory, benign, atypiaof undetermined significance, follicular lesion-neoplasm or suspicious for a neoplasm, suspicious for malignancy and malignant.Histopathological results of patients with incidental malignancy were presumed benign.Results: Among the 361 patients that were included in the study, 274 were female (75.9%), 87 were male(24.1%). Mean age of thepatients in the benign group was 49.1±12.5 years, and 48.6±13.5 years in the malignant group. It was found that FNAB’s sensitivitywas 83.9 %, specificity was 92.4%, false positive rate was 16.1% and false negative rate was 7.6%.Conclusion: FNAB is reported as the gold standard for preoperative evaluation of thyroid nodules. In our study, however, it wasseen that FNAB was not adequate alone teninfo:eu-repo/semantics/openAccessArticle2661100110310.5455/annalsmedres.2019.03.154316640
