title: [An early cancer in adenoma of the papilla of Vater].
abstract: A 61-year-old male was admitted to our hospital with a complaint of epigastric discomfort and back pain. Chronic pancreatitis was suspected after an abdominal US study. Therefore, an ERCP study was performed. Macroscopically, the papilla of Vater showed an irregular shaped swelling. An ERCP X-ray revealed no abnormal findings, but biopsied specimens from the papilla showed a well differentiated adenocarcinoma in the adenoma, so that a pancreatoduodenectomy was performed. The lesion was 15 x 9 x 6 mm in size, and a histological examination revealed that a minor portion of the tumor was a carcinoma while the major portion was an adenoma, and the invasion as being d0 panc0 n0.
