[Duodenal ulcer associated with a pyloric microgastrinoma and antropyloric focal gastrinosis (author's transl)].
In a patient with a duodenal ulcer, with acid hypersecretion and moderately disturbed gastrin secretion tests, immunocytochemical examination of the vagotomy-antrectomy specimen revealed a pyloric microgastrinoma (clinically silent and apparently benign) and focal antropyloric gastrinosis. These localised lesions represent a new variant of abnormalities affecting the gastrin cells in the context of hypersecretory duodenal ulcers.
