Epidermolysis bullosa acquisita presenting with localized facial blisters.

A 44-year-old woman presented with blisters on her face of 1-month's duration. A biopsy showed a subepidermal bulla with a dermal infiltrate of inflammatory cells and thick linear deposits of immunoreactants along the dermo-epidermal junction. Using Western immunoblots, the patient's IgG antibody was found to recognize type VII procollagen. Moderate doses of oral prednisolone resulted in a complete remission, without a recurrence for more than 3 years.
