A 73-year-old male visited our hospital for the upper abdominal pain in June 2005. CT and MRI findings detected a 60-mm cystic tumor in the pancreatic head, and nodular lesions were observed in the dilated main pancreatic duct on magnetic resonance cholangiopancreatography. Endoscopic findings revealed mucinous secretion from the greater duodenal papilla. We conducted pylorus-preserving pancreaticoduodenectomy with a diagnosis of main pancreatic duct-type intraductal papillary-mucinous carcinoma (IPMC). In January 2008, a cystic lesion was discovered in the hepatorenal boundary by imaging performed during follow-up, and surgery was performed. The patient underwent laparotomy that revealed a jelly-like substance present on the lower surface of the liver, and was disposed of as most as possible. On histopathological examination, it was diagnosed as pseudomyxoma peritonei associated with IPMC of the pancreas. It recurred in the splenic hilar region in February 2010. Similar surgery was performed and as much as possible of the jelly-like material was excised. As of March 2017, more than 10 years since the initial surgery, no recurrent lesion has occurred and the patient remains alive.
