Abstract
Renal cell carcinoma commonly matastasizes to the lung, bone and liver. However, metastasis to the pancreas is rare and often multiple, so diagnosis and treatment are difficult. Wereport a case of multiple pancreatic metastases from renal cell carcinoma 4 years after nephrectomy and resection of metastases to the brain and thyroid. A 52-year-old woman was admitted to our hospital with the chief complaint of bloody stool. Barium enema and colon fiberscopy revealed a tumor at the sigmoid colon. Abdominal CT and angiography demonstrated multiple hypervascular tumor at the pancreatic head and tail. Total pancreatectomy and sigmoidectomy were performed under the diagnosis of metastaticpancreatic tumor and carcinoma of the sigmoid colon. Histological examination confirmed it to be clear cell type renal cell carcinoma that had metastasized to the pancreas. Chemotherapy and radiation are not effective, and therefore, total pancreatectomy, when possible, could be the most useful treatment for this metastatic lesion.
