We present four cases of pediatric CG, and the first known reported case of identical twins with collagenous gastritis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This is a retrospective chart review of four cases of CG.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Four male patients all presented with anemia, three of which were initially diagnosed with eosinophilic gastritis.
