Presentation is variable, and symptoms fluctuate in intensity. Diagnosis can be challenging as it is mostly clinical. In severe cases, patients can present with anasarca secondary to protein\u2010losing enteropathy (PLE). The exact mechanism underlying PLE is incompletely understood. Here we report four cases of severe PLE caused by CMPA warranting endoscopic workup in whom histological expression was characterized by variable features along the gastrointestinal (GI) tract.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We report four cases of severe CMPA with PLE requiring extensive workup including endoscopy to exclude immune deficiency or congenital enteropathy.
