2. Figure 1
Macroscopic lesions found at upper endoscopy in paediatric patients with Crohn's disease. There was no drug intake nor Helicobacter infection suggesting the lesion is probably related to Crohn's disease. Ulcers (arrows) in the peripyloric region of the antrum (A). Severe ulcer and inflammation involving the whole gastric region (B). Duodenal ulcers (arrows) in the bulbar region (C). Aphthous lesion as an early sign of Crohn's disease (arrow) in the duodenal bulbar region (D).
