A case of Ménétrier's disease accompanied by severe hypogammaglobulinemia.

We describe a case of Ménétrier's disease accompanied by severe hypoproteinemia with marked decrease of gamma globulin. Roetogenograms and endoscopic findings of the upper gastrointestinal tract demonstrated enlarged gastric rugae and multiple small protuberances of the duodenal mucosa. Histological findings a gastric biopsy specimens showed mucosal thickening and hypertrophy. Plasminogen activator activities were increased in both gastric and jenunal mucosal biopsy specimens. Severe hypoproteinemia was proven by the Gordon test and by determination of protein content of gastric juice to be due to protein loss into the gastric lumen.
