[Hypergastrinaemia without detection of gastrinoma]. / Hypergastrinemie bez detekce gastrinomu.

We present a case-report of a woman with persisting gastric ulcers, who had elevated gastrin blood levels. First of all, a rare cause of hypergastrinaemia was excluded - a gastrinoma. It was not found despite of extensive investigation. Ulcers were repetitively biopted and transition of high grade dysplasia to adenocarcinoma was detected. Gastrin levels normalised after surgical antrectomia. Afterwards pernicious anaemia was diagnosed as the underlining cause of hypergastrinaemia.
