Cytologic and histologic results of FNA, CNB, and surgery were reviewed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>US revealed the following tumor features: oval-to-round (24\/24), solid (22\/24), smooth margin (21\/24), hypoechoic or marked hypoechogenicity (18\/24), and peri- and\/or intranodular vascularity (17\/17). Malignant US features such as marked hypoechogenicity ( n\u2009=\u20097) and a spiculated margin ( n\u2009=\u20093) were also observed. Final confirmation was by surgery in 22 patients and by CNB in two patients. All 19 patients who underwent FNA were initially misdiagnosed, including 12 with malignancies and five with atypia of undetermined significance. All four patients who underwent CNB were correctly diagnosed with HTT. The histology of CNB specimens suggested HTT, which was confirmed by immunostaining of MIB-1.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>HTT should be suspected when the cytological diagnosis of papillary thyroid carcinoma is made after FNA without malignant US findings.
