A Case of Resected Pancreatic Metastasis from Renal Cell Carcinoma 25 Years after Nephrectomy

Abstract

An 82-year-old-man, who had undergone left nephrectomy for primary renal cell carcinoma 25 years ago, was under follow-up at our cardiovascular surgery department because of an abdominal aortic aneurysm. Coincidentally, enhanced CT for the aneurysm revealed a pancreatic tumor showing early enhancement in the arterial phase. The patient had no symptoms, and laboratory data, including the endocrine profile, were within normal range. EUS-FNA suggested malignancy. Considering the past history, we considered the tumor as a metastatic pancreatic tumor from renal cell carcinoma. Distal pancreatectomy and splenectomy were therefore performed, and the postoperative course was uneventful. The pathological diagnosis was metastatic pancreatic tumor from clear-cell type renal cell carcinoma.
