ABSTRACT

We report a case of intraductal papillary mucinous tumor of the pancreas (IPMT) degenerated and fistulized into the stomach, the duodenum and the colon. Diagnoses of malignancy and fistulization were proven preoperatively. Pancreaticoduodenectomy extended to the body was performed. Pathological examination revealed a malignant IPMT with an invasive component. Of the 3 fistulizations tracts, both gastric and duodenal ones were malignant. To our knowledge, this is the first reported case of IPMT with colonic fistulization. Twelve months later, the patient is alive without signs of recurrence.
