Abstract
We experienced a rare case of esophageal involvement by crohn's disease, which showed various upper gastrointestinal endoscopic findings and successfully treated with steroid. A 49-year-old woman who had been treated for crohn's disease visited our hospital because of dysphagia. Upper gastrointestinal endoscopy shows aphthous erosions and punched-out ulcers in the esophagus, bamboo joint-like appearance in the stomach, and multiple nodular lesions in the duodenum. She was treated with proton pump inhibitor and steroid. Aphthous erosions and punched out ulcers in the esophagus improved, but bamboo joint-like appearance in the stomach, and multiple nodular lesions in the duodenum showed no significant changes.
