Morphologic And Endoscopic Evaluation Of Collagenous Gastritis, Annie Ashok, Ashlie L. Burkart, Md, Cm

Department of Pathology Honors Program Student Research Symposium

Collagenous gastritis (CG) is a rare gastrointestinal condition of unknown etiology and pathogenesis characterized by the presence of a gastric subepithelial collagen band of variable thickness. While little is known about the disease, children and young adults often present with anemia, abdominal pain, and nodular gastric mucosa on endoscopy. In contrast, adults often present with chronic watery diarrhea and normal gastric mucosa on endoscopy. Disease associations (usually in adult cases) include celiac disease, collagenous colitis, collagenous sprue, and lymphocytic colitis. This study aims to further characterize the clinical, endoscopic and morphologic spectrum of CG.
