Bilateral peripheral ulcerative keratitis associated with pyoderma gangrenosum.

ABSTRACT

PURPOSE: A 37-year-old Hispanic man with a history of chronic myelogenous leukemia was first seen with fever and preseptal cellulitis of this right orbit after a tooth extraction. METHODS: The patient subsequently developed bilateral, severe peripheral ulcerative keratitis. He was treated with systemic antibiotics for a presumed underlying infectious cause. Several painful, necrotizing skin lesions developed over his face, trunk, and extremities. RESULTS: Repeated skin biopsies of the necrotizing lesions were consistent with pyoderma gangrenosum. Both the skin lesions and peripheral ulcerative keratitis responded dramatically to systemic prednisone. CONCLUSIONS: Pyoderma gangrenosum should be included in the differential diagnosis of peripheral ulcerative keratitis.
