[Ménétrier's disease in pediatric patients secondary to cytomegalovirus infection: Presentation of two clinical cases in a high complexity center]

Ménétrier's disease is a protein losing gastroenteropathy. Defined as a rare entity with an unknown cause, most of the reported cases have been associated with viral infections. In pediatric patients, it is characterized by an acute onset with a benign and self-limiting course. It is characterized by thickened gastric folds that generally involve the body and the gastric fundus, associated with hypoalbuminemia due to the loss of serum protein through the mucosa. The following are two clinical cases of infant Ménétrier syndrome associated with cytomegalovirus infection.La enfermedad de Ménétrier es una gastroenteropatía perdedora de proteínas. Definida como una entidad rara y de causa desconocida, la mayoría de los casos reportados la han asociado a infecciones virales. En los pacientes pediátricos, presenta un comienzo agudo con un curso benigno y autolimitado. Se caracteriza por tener pliegues gástricos engrosados que, generalmente, involucran el cuerpo y el fundus gástrico, asociados a hipoalbuminemia, debido a la pérdida de proteína sérica a través de la mucosa. A continuación, se exponen dos casos clínicos de síndrome de Ménétrier infantil asociado a infección por citomegalovirus.
