We report the case of a 73-year-old Japanese woman suffering from antiepiligrin (laminin 5) cicatricial pemphigoid (CP) with typical clinical and immunopathological features. Histologically, the lesional mucous membrane showed a subepidermal blister formation. When indirect immunofluorescence techniques with skin split by 1 M NaCl as the substrate were used, the patient's serum reacted only to the dermal side. Immunoprecipitation studies demonstrated that the patient's serum contained IgG autoantibodies directed against a set of polypeptides that corresponded to epiligrin (laminin 5). After corticosteroids and immunosuppressive agents had been administered systemically, the patient's autoantibody titer decreased and the cutaneous and mucosal blister formations were suppressed. However, the ocular lesions persisted in spite of these therapeutic regimens. After combining these treatments with double-filtration plasmapheresis, the ocular lesions improved and showed almost no progression. Plasmapheresis may thus present a new option for the treatment of CP.
