[Corneal ulcer and Behçet disease. Apropos of a case].

We report a case of a peripheral corneal ulcer that occurred to a 33 years old female with a Behçet's disease. This patient had a previous history of viral keratoconjunctivitis with subepithelial nodules one year ago. The type, aspect and localization of the ulcer suggested an immunologic origin. The evolution was favourable after systemic and local steroid therapy. The other aetiologies of such ulcer are discussed by the authors.
