| Research Abstract |
Pancreatic intraductal papillary mucinous neoplasms (IPMNs) are mucin-producing
neoplasms of the main and/or branch pancreatic ducts. To assess differences between various IPMN subtypes, immunohistochemical markers of gastrointestinal cells were evaluated in 33 surgically treated IPMNs. IPMNs into gastric (n=17), intestinal (n=8) and mixed gastric and intestinal type (collision=7, composite=1). No differences in age or sex were observed among these types. Gastric pyloric and small intestinal differentiation are characteristic of gastric and intestinal type IPMN, respectively, and these two IPMN types may have distinct pathogenesis.
