title: [A case of autoimmune pancreatitis associated with hemorrhagic duodenal ulcers].
abstract: An 84-year-old man was diagnosed with IgG4-related autoimmune pancreatitis and sclerosing cholangitis with jaundice. Endoscopic nasobiliary drainage was performed, but hemorrhagic shock due to multiple duodenal ulcers occurred about a week later. After several endoscopic hemostasis, he was given corticosteroids. Histopathology of duodenal ulcer biopsies showed IgG4-positive plasma cell infiltration. Reports about duodenal ulcers with IgG4-related disease are very rare and we consider this case valuable.
