Abstract

Iron deficiency is the most common nutritional deficiency in children and adole-scents. Pediatric collagenous gastritis (CG) is a rare gastrointestinal disorder. Abdominal pain associated with iron deficiency anemia (IDA) is a common clinical symptom. We present three cases of pediatric CG diagnosed during the treatment of recurrent IDA. During esophagogastroduodenoscopy (EGD), nodularity of the gastric corpus was observed, which is a characteristic finding in pediatric patients with CG. Although pediatric CG could not be diagnosed by general EGD biopsy and patho-logical examination, it was diagnosed after suspecting pediatric CG and performing appropriate diagnostic tests. We recommend EGD for pediatric patients with re-current IDA, especially for those with gastrointestinal symptoms. Moreover, when performing EGD, conducting appropriate examinations for pediatric CG is necessary.
