title: [Duodenal endocrine tumor associated with ulcerous perforation].
abstract: A psammomatous endocrine tumor of the duodenum associated with a perforated duodenal ulcer, acute diffuse peritonitis and multiple organ failure is described. Histologic evaluation of the tumor shows a mixed pattern, with solid and glandular structures. Immunohistochemical stains further show cytoplasmic storage of gastrin and somatostatin. Apical CEA staining is also demonstrated in glandular areas of the tumor.
