Ménétrier's Disease

Ménétrier's disease causes giant folds of tissue to grow in the wall of the stomach. The tissue may be inflamed and may contain ulcers. The disease also causes glands in the stomach to waste away and causes the body to lose fluid containing a protein called albumin. Ménétrier's disease increases a person's risk of stomach cancer. People who have this rare, chronic disease are usually men between ages 30 and 60. The cause of the disease is unknown.

Ménétrier's disease is also called giant hypertrophic gastritis, protein losing gasteropathy, or hypertrophic gastropathy.
