Esophageal involvement in patients with Crohn's disease is uncommon. Histologic proof is rarely obtained by means of endoscopic biopsies. Moreover, the natural history of this condition and its response to therapy are largely unknown. We report a case of biopsy-proven esophageal Crohn's disease, which presented with a stricture of the distal third of the esophagus and was successfully treated by progressive endoscopic dilatation.
