title: Emerging gastritides.
abstract: The purpose of this review is to highlight two types of gastritis that have recently received much greater attention: lymphocytic gastritis and the gastritis associated with Crohn's disease. Lymphocytic gastritis is a distinctive pattern of inflammation that resembles that seen in celiac disease and lymphocytic colitis. It is associated with a diverse and unusual group of disorders in their own right, as well as having a possible relationship (real or phantom) with H. pylori infection. With respect to Crohn's disease, there is a growing recognition that, much more common than gastric granulomas, is the existence in one third or more of patients of a highly focal non-H. pylori gastritis. This recognition may help secure the diagnosis of Crohn's disease where it is equivocal, especially in children, in whom follow-up radiography and endoscopy cannot be done as readily as in adults.
