title: [Pancreatic intraductal papillary mucinous neoplasm: Case report and review of the literature].
abstract: Pancreatic intraductal papillary mucinous neoplasias (IPMN) are increasingly detected in medical diary practice because of increased awareness of their existence and because of increased use of cross-sectional imaging studies. IPMN are diagnosed incidentally in most cases and are classified as branch-duct IPMN, main-duct IPMN and combined-type IPMN. The last two types show a more aggressive biological behavior and surgery is recommended. Moreover, there are four subtypes of neoplastic epithelium in these tumours (intestinal, pancreatobiliary, gastric and oncocytic), which determine differences in the natural history of these neoplasms and this also seems to have prognostic relevance. We report a case of a patient who underwent a pancreatoduodenectomy due to a combined-type IPMN and whose anatomopathological study revealed an intestinal subtype IPMN with high grade dysplasia and colloid carcinoma. We also review the literature and describe the main aspects of this particular type ofcystic pancreatic tumours.
