We present a rare case in which a pancreatectomy was performed for a recurrent tumor in the remnant pancreas after a pancreaticoduodenectomy, and we review the associated literature. A 67-year old man underwent pancreaticoduodenectomy for pancreatic cancer on April 9, 2003. The tumor was composed of well differentiated adenocarcinoma and diagnosed as R0, pT2, pN1, pM0, pStage III according to UICC TNM classification. Five years and eight months later, his serum level of carcinoembryonic antigen was found to be elevated, and a computed tomography showed a low-density mass near the site of the pancreaticojejunostomy and dilatation of the jejunal stump. We conducted a total resection of the remnant pancreas including pancreaticojejunostomy, splenectomy and peripancreatic lymph node dissection without any residual macroscopic tumor. Histologically, it was diagnosed as a well differentiated adenocarcinoma, similar to the initial tumor. It is difficult to assess whether this tumor developing in the remnant pancreas was a local recurrence or a second primary cancer. However, we believe this tumor was a second primary tumor because of the long interval period and the absence of a neoplastic invasion in the resection margins of the initial specimens.
