The latter commonly arise from intestinal type IPMN and can be differentiated from PDAC-NOS by muconodular invasion type [13]with scant tumor cell clusters, and by their expression of the intestinal epithelial marker MUC2 and intestinal differentiation marker CDX2 [12, 14]. Here, CDX2 is linked to pancreatic intraductal papillary-mucinous neoplasm.
