BACKGROUND AND AIMS: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) sampling has become standard practice for the diagnosis of @entity344 . The aim of this study was to determine the utility of EUS-guided FNA cytology in the diagnosis of deeply seated @entity1819 . MATERIALS AND METHODS: Thirteen @entity1 with deeply seated @entity1819 were diagnosed by EUS-FNA. Adequate cytology material was present in all cases. Cell blocks were available in 10 cases. Surgical resections were performed in 8 cases. Immunohistochemical (IHC) studies were done on cell blocks in 9 cases and on 6 resected specimens. Seven cases has proved to be @entity5 ( @entity5 ), in four of them, cell blocks were available, and resection for @entity5 was performed in 5 cases. IHC stains that were performed in cytology, as well as resection specimens, revealed similar results in each @entity1 . CONCLUSION: EUS-FNA cytology, when combined with a histologic assessment of cell blocks provides accurate and efficient tissue diagnosis of a wide variety of deeply seated @entity1819 .
