A RESECTED CASE OF PANCREATIC TUMOR METASTASIZED FROM RENAL CELL CARCINOMA DIAGNOSED BY ENDOSCOPIC BIOPSY THROUGH THE MAIN PANCREATIC DUCT

Abstract

A 66-year-old man was referred to our hospital with complaints of itching and transient jaundice. A right nephrectomy had been performed 8 months before admission for renal cell carcinoma. Endoscopic retrograde cholangiopancreatography (ERCP) showed a highly dilated main pancreatic duct with a filling defect. Biopsy specimens obtained through the main pancreatic duct revealed renal cell carcinoma. It was composed of clear cell and granular cell types. There was no evidence of hepatic or nodal metastasis on CT. Total pancreatectomy preserving the pylorus was performed. There are few reports on the diagnostic value of duodenoscopic biopsy through the main pancreatic duct regarding pancreatic metastasis from renal cell carcinoma.
