The Authors report the case of a 83 year old woman with large cystic polyps of the stomach. Gastric cystic polyps are polypoid lesions which may develop following functional disorders such as increased mucosal stimulation by gastrin, or excessive retention of gastric secretions. The incidence of these polyps is variable, depending on their being underestimated since they are not always macroscopically visible. The case here reported is very interesting not only for the number of lesions (over 50), but also for their size (5-25 mm in diameter).
