Ménétrier disease is a rare, acquired, premalignant disease of the stomach characterized by massive gastric folds, gastric hyperplasia, excessive mucus production with resultant protein loss, and little or no acid production (achlorhydria). The disorder is associated with excessive secretion of transforming growth factor alpha (TGF-α). It is named after French physician Pierre Eugène Ménétrier (1859–1935).
