Left: 23 year old man with abdominal pain and known Crohn's colitis, and Right: 32 year old woman with nausea, vomiting, abdominal pain and known severe Crohn's ileocolitis. In both patients, upper endoscopy was grossly normal, however in both patients biopsies obtained from gastric antrum revealed microscopic chronic active inflammation with granulomas, consistent with gastric Crohn's. Images are included here to illustrate that active disease may not be grossly visible.
