A 74-year-old woman was admitted to the hospital for an exacerbation of congestive heart failure. For a year, she had had a venous stasis ulcer on the lateral left lower leg. During admission, topical bacitracin and a compression bandage were applied to the ulcer. Two days later, the patient complained of severe itching and burning, and the bandages were removed. Diffuse erythema surrounded the wound, with tense bullae in some areas. The erythema was extensive but limited to the areas covered by the bandages.
