Pathologic View of Intraductal Papillary Mucinous Neoplasm

Among pancreatic cystic lesions, mucinous neoplasm (MCN) and intraductal papillary (IPMN) of the pancreas are precursor lesions adenocarcinoma. IPMN is characterized by proliferation mucin-producing epithelial cells that exhibit various degrees dysplasia. classified as main duct type (MD-IPMN), mixed branch (BD-IPMN) according to location involvement, into four histological subtypes (gastric, intestinal, pancreatobiliary, oncocytic) histomorphological immunohistochemical characteristics. Most patients with MD-IPMN undergo tumor resection due moderate high risk malignancy. Patients BD-IPMN who do not may develop malignant change, concomitant separate cancer occurs in 2-10% IPMN. should careful surveillance including endoscopic ultrasound sonography for early detection change cancer.
