Cytologic features of XXXX .

@entity1 @entity3123 @entity788 @entity4294 @entity5
Although a number of reports have demonstrated the accuracy of fine needle aspiration (FNA) in the diagnosis of nonendocrine @entity3123 , the cytomorphology of @entity4294 ( @entity788 ) is not well defined. This paper describes the cytologic features of three histologically confirmed cases of @entity4294 . The three @entity5 occurred in one @entity1 and two @entity1 , who were 63, 64 and 70 years of age, respectively. Each @entity1 underwent FNA of pancreatic mass with computed body tomography guidance. The aspirates contained large numbers of @entity5 cells in two cases and a smaller number in one case. The cells, distributed singly and in small groups, were small and round or polygonal, with scant to more often abundant, dense or granular cytoplasm. The nuclei were often located eccentrically and were round to oval, with smooth nuclear borders and finely stippled chromatin. Many nuclei contained a single nucleolus. Multinucleated cells were present and generally contained two or three nuclei. Although the diagnosis of @entity4294 in fine needle aspirates is difficult, the cytomorphologic features of these @entity5 are sufficiently distinctive to suggest the diagnosis, especially when a relatively monomorphic population composed predominantly of single cells is present.
