In 1996, IPMN was defined by the World Health Organization as “an intraductal papillary mucin-producing neoplasm, arising in the main pancreatic duct or its major branches” (, 6). IPMN represents a spectrum of disease from small benign adenomas through aggressive and lethal invasive carcinomas.

Intraductal Papillary Mucinous Neoplasm of the Pancreas (IPMN) First described in the mid 1980's, IPMN is a cystic neoplasm of the pancreas that is being diagnosed with increasing frequency as an incidental finding on an MRI or CT scan of the abdomen done for some other indication. IPMN is a slow growing tumor that has malignant potential.

Survival of patients with IPMN, even when malignant and invasive, can be quite good. As with MCN, patients with borderline tumors or carcinoma in situ are usually cured. With invasive carcinoma, the 5 and 10-year survival is 60% and 50% which is much better than typical pancreatic adenocarcinoma. Intraductal papillary mucinous neoplasms are one of a number of mucinous tumors of the pancreas and can be further divided both histologically and with respect to their macroscopic appearance 5. They are uncommon ductal epithelial tumors comprising approximately 10-15% of cystic pancreatic neoplasms.

Intraductal papillary mucinous neoplasms or tumors (IPMNs or IMPTs) are epithelial pancreatic cystic tumors of mucin-producing cells that arise from the pancreatic ducts. They are most commonly seen in elderly patients. Patient Information and Health Disclaimer. Welcome to this online community resource!

In IPMN preoperative studies will show a dilated pancreatic duct in the main duct variety, but not necessarily the intraductal mass, which is often small. Because of the overproduction of mucus, dilation can occur both proximally and distal to the tumor, making location problematic.

Hence, despite high quality data, challenges remain in routine clinical practice for the surveillance and optimal management of IPMN [1]. IPMN History In 1982, Ohhashi . main duct type (MD-IPMN), branch duct type (BD-IPMN) and mixed type [6]. According to previous data, the mean frequency of malignancy in MD-IPMN is approximately 60-100%, whereas in BD-IPMN, it is approximately 25% [7, 8].

Pankreatiske pseudocyster defineres som lokaliserede, amylase-rige væskeansamlinger i eller ved pankreas og omgivet af en fibrøs væg uden epitelbeklædning Intraductal papillary mucinous neoplasms (IPMN) are mucin producing cystic neoplasms of the pancreas histologically classified as having non-invasive and invasive components.

Dessa utgör endast 4 % av det totala antalet celler i pankreas.Duktal pankreascancer är oftast lokaliserad till kaput, men kan också uppstå i korpus och kauda (10 % av fallen). Metastasering till lymfkörtlar sker mycket tidigt. Ampullär cancer utgår från papilla eller ampulla Vateri […] Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a distinct clinicopathologic entity that is being recognized with increasing frequency. In 25%–44% of IPMNs treated with surgical resection, associated invasive carcinoma has been reported. Evidence-based guidelines on the management of pancreatic cystic neoplasms (PCN) are lacking.

It can occur in both men and women older than 50. Depending on its location and other factors, IPMN may require surgical removal. 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). Intraductal papillary mucinous neoplasms are also characterized by the production of thick fluid, or "mucin", by the tumor cells.
