Figure 5: (a) Case 5- EUS showing 4.5 cm x 4.2 cm hypo echoic lesion in uncinate process. (b) Case 5- A. EUS-FNA smear shows a long pseudopapillary structure characteristic of solid-pseudopapillary neoplasm.(Pap stain, ×400) B. The cellblock section shows a tumor cell group in a cystic background. (H and E stain, ×400) C. Immunohistochemical (IHC) stain for synaptophysin is positive in the tumor cells (IHC stain, ×400). D. Immunohistochemical stain for beta-catenin shows positive nuclear staining in the tumor cells. (IHC stain, ×400)
