[Stomach neurinoma].

Between 10 and 15% of all benign nonepithelial tumors of the stomach are neurinoma. The majority of these tumors originating from the plexus myentericus do not cause clinical symptoms. They become clinically important because of complications like hemorrhage, perforation or displacement of neighbouring organs. Typical clinical symptoms, laboratory data, radiological or endoscopic findings do not exist. The diagnosis neurinoma can only be established by histological examination; differentiation of myogenic tumors is often difficult. The surgical procedure has to take into account extension, localisation, and relation of the tumor to the stomach wall. If multiple neurinoma extending from the cardia to the pylorus are present total gastrectomy may be necessary.
