Ultrasound (US)-guided fine-needle aspiration cytology (FNAC) is now widely accepted as a diagnostic procedure for @entity1558 . Along with its advantages, US-guided FNAC also has some pitfalls. The recognition of these pitfalls for this procedure is extremely important for the strict management of the disease. We retrospectively investigated the diagnostic potential and pitfalls of US-guided FNAC in the diagnosis of @entity1558 . This study consisted of 348 aspirated samples from 274 @entity0 . The rate of sufficient aspirates was 74% after a single aspiration, while sufficient materials were finally obtained from 93% of the @entity5 by repeated @entity1173 . The rate was lower in @entity5 measuring less than 10 mm in diameter (62%), and in sclerosing @entity3923 (25%). The sensitivity of FNAC was 65%, the specificity was 75%, the border diagnosis rate was 18%, and the positive predictive value was 92%. The false-negative rate was higher in noninvasive @entity189 (45%). The border diagnosis rate was also higher in @entity5223 (29%). There were also five false-positive cases. Limited to nonpalpable lesions, the sufficient aspirates rate was 70% and the accuracy was 67%.
