[Ulcer disease of endocrine origin associated with a non-gastrin substance]

The purpose of this paper is to report on a form of duodenal ulceration associated with a major hypersecretion that we described in 1984. This entity belongs to the group of endocrine duodenal ulcer diatheses of which the Zollinger-Ellison Syndrome (ZES) in the prototype. We have recently in 1989 reported a series of patients with clinical and pathologic features indistinguishable from those of the Zollinger-Ellison syndrome but without hypergastrinemia. We have also found that the plasma and the tumor tissues of these patients contains a potent non-gastrin secretagogue.
