Case. Iron deficiency anemia is the most common and usually single laboratory finding without any complaint at the time of diagnosis. This entity should be well-known so that we can examine and refer the patient to a pediatric gastroenterologist for differential diagnosis.

Conclusions. The histopathological evaluation, albeit invasive, is essential to exclude this diagnosis. We present a 13-year-old girl with intractable iron deficiency anemia due to CG. Keywords : collagenous gastritis, iron deficiency, child, pathology, endoscopy
