For a long time they were misdiagnosed as mucinous cystadenocarcinoma, ductal adenocarcinoma in situ, or chronic pancreatitis. The latest WHO classification of tumors of the digestive system (2019) has introduced new concepts for the stratification of intraductal neoplasms of the pancreas, mostly based on molecular genetics and malignant potential. The tumor produces an excessive amount of mucin and results in progressive dilation of the main pancreatic duct or cystic dilation of the branch ducts, depending on the location of the tumor.

Classification Classification based on function. Imaging studies showed that the pancreatic tissue encircled the descending part of the duodenum and that a 30-mm-diameter cystic tumor was present in the annular segment, leading to the diagnosis of pancreatic IPMN. IPMN occurs more commonly in men, with the mean age at diagnosis between 64 and 67 years old. Pathology Outlines - Intraductal tubulopapillary neoplasm The criteria usually involve anatomic .

Core Tip: Intraductal papillary mucinous neoplasms (IPMNs) account about 1% of all pancreatic neoplasms and 25% of cystic neoplasms. Intraductal tumors have been referred to by different names (mucinous ductal ectasia, papillary adenocarcinoma, ductectatic tumor, intraductal mucin-hypersecreting neoplasm, mucinous villous adenomatosis) (, 4); however, in 1997, the unified term intraductal papillary mucinous tumor was adopted (, 5). The early detection of the disease relies on the detection and surveillance of high-risk individuals. 1 It is increasingly detected by improved CT and magnetic resonance imaging technology. The remaining risks of PDAC progression in the remnant pancreas after partial pancreatectomy to remove the primary IPMN lesion. Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a distinct clinicopathologic entity that is being recognized with increasing frequency.

Intraductal papillary mucinous neoplasms or tumours (IPMNs or IMPTs) are epithelial pancreatic cystic tumours of mucin-producing cells that arise from the pancreatic ducts. Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a unique clinicopathologic entity characterized by cystic dilatation of the pancreatic duct, mucous production, and papillary growth. . We conclude that intraductal oncocytic papillary neoplasm is a distinctive pancreatic tumor that is usually intraductal but may develop invasive carcinoma and should be treated with complete resection.

The only chance of cure for pancreatic cancer depends on its early detection and appropriate resection. The patients were noted to have dilated main pancreatic ducts, patulous ampullary orifices, and mucus secretion from the pancreatic duct [ 6 ]. IPMN is divided into two types, the main duct type and the branch duct type. Only one-third of all patients are symptomatic, and others are diagnosed by chance. "Intraductal papillary mucinous tumor" is now the preferred term to describe a spectrum of proliferation of the pancreatic ductal epithelium. Most branch-type IPMNs are benign, while the other 2 types . See Molecular / cytogenetics description.

They have the potential to become malignant, for that reason; diagnostic criteria have been published to identify which patients will require surgical resection. Intraductal papillary mucinous neoplasm (IPMN) is an increasingly recognized cystic neoplasm of the pancreas, histologically classified by the degree of epithelial atypia and by the presence or absence of invasion of the cyst wall. Since this type of neoplasm can be small and asymptomatic, the true incidence of IPMN is not known, but it is believed to be increasing [ 1 , 3 ]. Much knowledge about the unique biological characteristics of intraductal papillary mucinous neoplasms (IPMN) of the pancreas has been gained since its initial characterization by the WHO more than 2 decades ago.
