A new biliary duct (BD) stricture raises questions about the presence of malignancy, especially with a history of metastatic pancreatic cancer. A few cases of colloid carcinoma (CC) of the pancreas have been published, but none have described recurrence in the biliary tract. We report a case of intrahepatic biliary CC that recurred after two years after the last dose of immunotherapy for pancreatic CC. In addition to a unique biliary cancer case presentation, this case raises awareness of the best strategy for cancer surveillance.
Keywords: biliary duct; colloid carcinoma; jaundice; pancreas; recurrence.
