| Summary: | Background: Metastases of renal cell carcinoma (RCC) to the pancreas are rare, whereas recurrence of pancreatic ductal adenocarcinoma (PDA) or a primary periampullary cancer is far more common. The time elapsed between a primary tumor and a new mass can aid in differentiation between the two.
Presentation: A 70-year-old man with a history of RCC status after left nephrectomy and ampullary adenocarcinoma status after pancreaticoduodenectomy presents with an incidentally found mass in his remnant pancreas. Resection of the mass via completion pancreatectomy yielded pathology consistent with metastatic RCC.
Conclusions: Metastases of RCC to the pancreas often present many years after a primary resection. Conversely, recurrent PDA often presents within 5 years of resection. Resection of RCC metastases yields better survival than resection of recurrent PDA, which is controversial. We recommend resection of suspected isolated pancreatic RCC metastases due to known favorable outcomes.
