Physical examination is remarkable for oral aphthous ulcers, mild right lower quadrant tenderness, and perianal skin tag at six o'clock position. Further laboratory work up reveals anemia (hemoglobin 7.2 g/dL) and elevated erythrocyte sedimentation rate (41 mm/hr). She was referred to pediatric gastroenterology and underwent an esophagogastroduodenoscopy and colonoscopy, which was visually and histologically remarkable for gastritis, duodenitis, pan-colitis, and terminal ileitis (Figure 59-1 and 59-2). She was diagnosed with Crohn disease.
