A 41-year-old woman with a chronic atrophic gastritis after endoscopic investigation diagnosed a carcinoid at the corpus of the stomach. There were more lesions in the mucosa of the stomach in the form of dysplasias. The labor investigation indicated an hypergastrinaemia. We performed a resection of the basis of the carcinoid. It has shown to be histologically tumor-free as the rest of the stomach. A gastrectomy was not necessary. After resection the patient was under therapy with vitamin B-12. The level of gastrin in blood was normal under this treatment. Two years later the patient remained symptom-free. Regular endoscopic investigations show a stagnation of the growth of the dysplastic lesions of the mucosa of the stomach.
