Lymphocytic gastritis and protein-losing gastropathy.

Lymphocytic gastritis is a histopathological entity of unknown aetiology which is characterized by dense surface and foveolar epithelial T-cell infiltration. We report here an uncommon clinical presentation in a young female presenting with unexplained recurrent weight loss and peripheral oedema. Endoscopic and histological features before and after successful therapy with omeprazole are described.
