title: [Duodenal ulcer and pyloric micro-gastrinoma. A report of one case (author's transl)].
abstract: We report a case of micro-gastrinoma associated with a duodenal ulcer. This ulcer was severe and a gastrectomy (Finsterer) was performed. Pathologic examination showed a "carcinoid islet cell-tumor" with argyrophil granules in the cells' cytoplasme and ultrastructural studies confirmed neurosecretory granules with dense central core. Using the immunofluorescence and immunoperoxydase technic with several anti sera against polypeptide hormones we were able to show it was a pure gastrinoma. We presume this association is a new entity in gastrin-cells pathology.
