A case of Ménétrier disease in a child.

Ménétrier disease is a protein-losing gastroenteropathy often misdiagnosed in the pediatric population. The disease is characterized by hypoalbuminemia secondary to protein loss through the gastrointestinal mucosa and resultant peripheral edema. It is important for emergency department practitioners to consider this diagnosis in the differential diagnosis for edema and low albumin levels in pediatric patients. We present a case report of Ménétrier disease in an edematous child and a brief review.
