Abstract

We experienced a rare case of main duct intraductal papillary mucinous neoplasm (MD-IPMN) without overt mucin production. Histological findings classified the tumor as high-grade dysplasia of pancreatobiliary-type IPMN that has been reported to show high malignant potential with a property to disseminate extensively into pancreatic ducts.
