Collagenous gastritis (CG) is a rare disease, which is characterized by subepithelial deposition of collagen in the gastric mucosa, surface epithelial injury, and a lamina propria inflammatory infiltrate. Approximately 100 cases of CG have been reported in the literature. We report another case of a young girl who presented to us with severe anemia and chronic diarrhea and was diagnosed with CG based on clinical features and endoscopic and pathologic findings. She was successfully managed with oral iron, sucralfate, and proton pump inhibitor therapy.
