Gastrointest Endosc 1998; 48:164-171. Within that group of cystic neoplasms, intraductal papillary mucinous tumors (IPMTs) can be distinguished from mucinous cystic neoplasms, serous cystic neoplasms, and pseudopapillary cystic tumors. Background: Adjuvant treatment for pancreatic adenocarcinoma has been shown to improve survival. However, reported outcomes after surgical resection for IPMN show that once the tumor progresses to invasive intraductal papillary mucinous carcinoma (IPMC), recurrence is not uncommon. Intraductal Papillary Mucinous Neoplasm (IPMN) of Pancreas is an exocrine, cystic tumor that grows within the pancreatic duct. 1 They were first described in the pancreas in 1996 by Adsay et al 2 and are now classified as 1 of 4 histologic subtypes of intraductal papillary mucinous neoplasm (IPMN) within the pancreas.

Intraductal papillary mucinous neoplasms are one of a number of mucinous tumours of the pancreas and can be further divided both histologically and with respect to their macroscopic appearance 5. The current treatment strategy for intraductal papillary mucinous neoplasms (IPMNs), based on the international consensus guideline, has been accepted widely. IPNBs are mainly found in patients from Far Eastern areas, where hepatolithiasis and clonorchiasis are endemic. Its epidemiology, natural history and proper management remain in a state of flux, and therefore surgical treatment is not standarized.

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a distinct entity characterized by papillary proliferations of mucin-producing epithelial cells with excessive mucus production and cystic dilatation of the pancreatic ducts. 3 The other 3 histologic subtypes of IPMN are gastric-type . They have the potential to become malignant, for that reason; diagnostic criteria have been published to identify which patients will require surgical resection. A recommendation has been made in recent years to call these tumours intraductal papillary neoplasm of the bile duct (IPNB). IPMN cells are characterized by the secretion of mucus, and are typically located in the head region of the pancreas Intraductal papillary mucinous neoplasm (IPMN) is a cystic tumor that grows within the pancreatic ducts and is composed of mucin-producing cells.

IPMN has the potential to progress to an invasive cancer. WHO classifi cation in 2000 [4] , the two neoplasms were renamed as intraductal papillary mucinous neoplasm (IPMN) ( fi g. 1 ) and mucinous cystic neoplasm (MCN) ( fi g. 2 ), respectively. Identification of IPMN at high risk for malignant transformation is important for the prevention and early treatment of pancreatic cancer. Intraductal papillary mucinous neoplasms (IPMN) are cystic neoplasms of the pancreas that grow within the pancreatic ducts and produce mucin. Visual survey of surgical pathology with 11,460 high-quality images of benign and malignant neoplasms & related entities. Crossref, Medline . Mucinous cystic neoplasm (MCN), also called hepatobiliary cystadenoma, is a solitary, multilocular cystic neoplasm that can arise within the liver, extrahepatic bile ducts or gallbladder. Based on imaging in 195 such patients, we chose surgery as initial treatment for 54, and periodic evaluation over 6 to 192 months (mean, 52) for 141. Since then much has been learnt about the clinical, radiographic, and histological charac-teristics of these neoplasms. The etiology is unknown, but increasing evidence suggests the involvement of several tumorigenesis pathways, including an association with hereditary syndromes. Hepatogastroenterology 2000;47(34):1129-1134.

Intraductal papillary mucinous neoplasm (IPMN) is characterized by cystic dilatation of the main and/or branch pancreatic duct. Intraductal papillary mucinous neoplasms are tumors that grow within the pancreatic ducts (the pancreatic ducts are the "tubes" within the pancreas that are used to transport fluids to the bowel to help with digestion). These lesions represent nowadays a relatively new clinical entity and in many aspects remain poorly understood. We retrospectively investigated the incidence of pancreatic ductal adenocarcinoma among patients with intraductal papillary mucinous neoplasms of the pancreas. Magnetic resonance imaging is the most useful approach for most IPMNs.

Patients Sixty-four consecutive patients with a pathological diagnosis of IPMN.. Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas. Medline, Google Scholar; 10 Bernard P, Scoazec JY, Joubert M, et al. N2 - Intraductal papillary mucinous neoplasms (IPMNs) are cystic pancreatic tumors that arise from the pancreatic ducts and are increasingly reported worldwide. Identification of predictive factors for differentiating IPMC from benign IPMNs would assist in providing appropriate treatment. Ann Surg 1998; 228:685-691. Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma that is characterized by intraductal growth and better outcomes compared with common cholangiocarcinoma. Colloid carcinoma derived from intraductal papillary mucinous neoplasm (IPMN) of the pancreatic head with prominent calcification is exceedingly rare. Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. Crossref, Medline, Google Scholar; 33 Doi R, Fujimoto K, Wada M, Imamura M. Surgical management of intraductal papillary mucinous tumor of the pancreas. Since their first description in 1987, these rare tumors have been increasingly recognized [].The prevalence of IPMN is about 26 per 100,000 people; however, they are more common in the elderly, with an incidence of 99 per 100,000 people in those over the age of 60 [2, 3].
