A 78-year-old man who underwent right nephrectomy for renal cell carcinoma (RCC) 18 years ago visited our hospital complaining of abdominal pain. Imaging revealed that the pancreatic head tumor obstructed the Santorini duct. We suspected a pancreatic intraductal tumor, such as an intraductal tubulopapillary neoplasm or intraductal papillary mucinous neoplasm. Thus, the patient underwent subtotal stomach-preserving pancreaticoduodenectomy. Pathological findings confirmed the diagnosis of metastatic RCC. Herein, we report a case of pancreatic metastasis of an RCC that presented with a tumor in the pancreatic duct.
