Two cases of collagenous gastritis diagnosed during the investigation of anemia

Abstract

This paper discusses two cases of collagenous gastritis. The patient in Case 1 was an 18-year-old male referred to our hospital for the investigation of iron-deficiency anemia. Endoscopic examination revealed a granular mucosa and island-like nodule in the gastric body. The pathological examination of the depressed mucosa revealed a thickened subepithelial collagen band, and collagenous gastritis was diagnosed. The patient in Case 2, a 14-year-old boy diagnosed with gastric polyposis at the age of 10 years, was referred to our pediatric surgery department to investigate iron-deficiency anemia. An endoscopic examination revealed granular mucosa and island-like nodule in the gastric antrum and body. Pathological examination of the depressed mucosa revealed a thickened subepithelial collagen band, and collagenous gastritis was diagnosed.
