Online published on 15 December, 2017. Abstract Background Fine needle aspiration (FNA) is a reliable method in the initial assessment of thyroid nodules. This study evaluated the accuracy of fine needle aspiration cytology (FNAC) in cases of follicular neoplasm (FN) on the basis of histologic diagnosis, and reviewed the cytologic findings of FN according to the FNAC. Method Among the 50 cases diagnosed with thyroid Follicular Neoplasm by FNAC during the 3 year period from October 2013 to September 2016, 27 cases that had undergone thyroid surgery were available for review. Cytologic diagnosis was compared with the histologic diagnosis of each case. Results Among the 27 cases with a cytologic diagnosis of thyroid FN, histologic diagnosiswas as follows: 16 follicular adenomas (59.3%), 2 Hurthle cell adenomas (7.4%), 1 follicularcarcinomas (3.7%), 5 nodular goitres (18.5%), 1 papillary carcinomas (3.7%), and 1 Hashimoto'sthyroiditis (3.7%), resulting in a diagnostic accuracy of FNAC for thyroid FN of 70.4%. Conclusion This study shows that FNAC for thyroid FN is a useful primary screening method because when FN is diagnosed by FNAC, the rate of FN histological diagnosis is relatively high and however, adequate sampling and experience is a prerequisite for this procedure.
