Fine-needle aspiration (FNA) of @entity660 with ultrasound or computed tomographic, and recently echo-endocopic guidance has become commonplace to diagnose the nature of a @entity660 . It is specially usefull in diagnosing solid @entity5 . Most often, FNA is performed to confirm a diagnosis of @entity420 . The aspirate shows cellular clusters with high nuclear-to cytoplasmic ratio, overlapping nuclei and prominant macronucleoli. The cytologic features that permit a @entity5 are loose cellular aggregates with round nuclei, evently dispersed nuclear chromatin, a moderate amount of amphophilic cytoplasm and rosette formation. Immunocytochemistry can provide additional confirmatory information. Difficulties are encountered in diagnosing @entity5 . The major cytologic differences between serous and @entity5 are the absence of @entity3558 and presence of low cuboidal glycogen-containing cells in the @entity652 vs the presence of goblet cells in the @entity5 . Except for the presence of @entity39 , and in the absence of obvious malignant cytologic features, it is impossible to predict the behaviour of mucinous @entity5 . The lower accuracy for @entity5 can be attributed to predominantly bloody specimens and limited cellularity. These problems illustrate the importance of knowing the clinical and radiological features of @entity788 .
