Intraductal papillary mucinous neoplasm (IPMN) IPMN is a papillary neoplasm that arises within the main pancreatic duct (MPD) or its branches. IPMN is characterized by Intraductal, papillomatous growth pattern Excessive mucin secretion Excessive mucin secretion results in progressive ductal dilatation and cyst formation IPMNs are most commonly localized to the head of the pancreas, but they may occur at any site along the pancreatic ductal system. IPMTs are premalignant and may histologically demonstrate areas ranging from hyperplasia to carcinoma within a single tumor. IPMTs which is positive for MUG 2 (Intestinal-type secretory mucin) may form an adenocarcinoma (ductal adenocarcinoma).
