Localized epidermolysis bullosa acquisita of the esophagus in a patient with Crohn's disease.
Epidermolysis bullosa acquisita is a rare autoimmune subepidermal bullous disease that affects both the skin and mucosae and is frequently associated with Crohn's disease. We report the case of a 27-yr-old man with Crohn's disease who presented with localized epidermolysis bullosa acquisita of the esophagus, without any other mucosal or cutaneous lesions. The patient was successfully treated with sulfasalazine.
