Key Points

This case report aims to highlight the occurrence of pancreatic ductal adenocarcinoma following surgery for distal bile duct carcinoma.
Presented a rare case of diffuse-type pancreatic cancer post-resection for bile duct carcinoma.
Detailed the timeline of cancer development following pancreaticoduodenectomy.
Reviewed the implications of obstructive pancreatitis in cancer recurrence.
Diffuse-type pancreatic cancer developed 16 months post-surgery for distal bile duct carcinoma.
The rapid occurrence of this cancer type is considered extremely rare following such surgical intervention.

Abstract

INTRODUCTION: Distal bile duct carcinoma (DBDC) and pancreatic ductal adenocarcinoma (PDAC) are aggressive malignancies; however, their metachronous occurrence within a short postoperative timeframe is extremely rare. We present an extremely rare case of diffuse-type PDAC that rapidly developed only 16 months after curative resection of DBDC.
