title: Helicobacter pylori and gastric lymphonodular hyperplasia in children.
abstract: The association of gastric lymphonodular hyperplasia and Helicobacter pylori infection has been reported only in children. Lymphonodular hyperplasia of the stomach is a well known radiographic and endoscopic entity. Over the past three decades, it has been associated with many conditions, ranging from a normal variant to a premalignant lesion. We have recently encountered five children with gastric lymphonodular hyperplasia, all of whom had H. pylori infection of the antrum. The literature regarding this association is reviewed, and a possible explanation for this age-dependent expression of H. pylori infection is offered.
