Pediatric Helicobacter pylori gastropathy demonstrates a unique pattern of gastric foveolar hyperplasia.

An objective, quantitative approach to measuring foveolar hyperplasia in adults was successfully applied to pediatric biopsies and yielded a richer characterization of gastric pathology in children. Foveolar hyperplasia appears to be a generalized phenomenon in the presence of pediatric Helicobacter pylori gastritis but is limited to the antrum in non-Helicobacter pylori gastropathy.
