[A rare cause of peripheral edema: exudative lymphocytic gastritis induced hypoprotidemia].

Diagnosis of edema secondary to hypoprotidemia but without nutritional, renal, hepatic or cardiac cause, must consider exudative digestive disease, of which the lymphocytic gastritis, as the authors report here a new observation diagnosed in a 73 year-old woman. Gastroscopy reveals varioliform gastritis and biopsy demonstrates diffuse infiltration of the gastric epithelium by lymphocytes, making of it a real histopathologic entity among the gastropathies. Etiology and pathogeny remain still unknown but proton pump gastric inhibitors are an effective treatment.
