Pancreatitis with coexistent pancreatic duct stone and carcinoma. Early diagnosis by endoscopic retrograde pancreatography.

We had a patient with cancer of the pancreas that was diagnosed by endoscopic retrograde pancreatography where conventional diagnostic methods (including arteriography) were negative. Pancreatic resection was possible and examination of the surgical specimen showed microscopic adenocarcinoma coexistent with an intraductal stone and pancreatitis.
