The intraductal papillary mucinous neoplasm (IPMN) is a proven precursory lesion of pancreatic cancer, maybe the most important. The pancreatic cancer is a pathology associated with high rates of mortality. The IPMN develops from the epithelial ductal pancreatic cells and it expresses as cystic dilation of the main pancreatic duct and/or its branches, being part of the differential diagnosis of the cystic pancreatic masses. The identification of “invasive” and high-grade dysplasia IPMN lesions is imperiously necessary for a correct therapeutic approach; the pancreatic complementary resection being indicated in all cases with high-grade dysplasia upon the surgical margins of frozen section examinations.
