The Great Mimicker of Gastric Cancer: A Case Report of Ménétrier's Disease.

ABSTRACT

This is the case of a 52-year-old Indian lady who presented with hematemesis, severe anemia, and an abdominal lump in cardiac failure. On radiographic evaluation, the lesion appeared to be gross circumferential asymmetric proximal gastric wall thickening, with suspicion of gastric lymphoma or tubercular hypertrophic gastritis. After stabilization with multiple transfusions, she underwent proximal D2 gastrectomy with esophago-gastric anastomosis and a total splenectomy. Grossly, the gastric rugae appeared to be hypertrophied and firm. No growth was identified grossly; however, necrotic areas were identified at the distal end. Microscopic examination of multiple sections studied showed significant foveolar hyperplasia, tortuous glands, and a few cystically dilated foveolar glands, which were limited up to the muscle layer. Mild serosal congestion was seen. No atypia or invasion was seen. An impression to consider is the possibility of Ménétrier's disease (MD). MD is an acquired protein-losing enteropathy with giant gastric rugal folds, decreased acid secretion, and increased gastric mucous production. Radiographically, endoscopically, and grossly, the condition can be confused with malignant lymphoma or carcinoma. It is difficult to diagnose, and histopathological confirmation of the resected specimen is needed for a definitive diagnosis. Our intention in presenting this case is to emphasize that MD can present as massive hematemesis and should be considered in a differential diagnosis. Surgical treatment by total or partial gastrectomy is recommended for cases with persistent, debilitating symptoms or a risk of cancer.
