In this paper, we describe a 69‐year‐old Japanese woman with localized pemphigoid. Direct immunofluorescence study showed linear IgG, IgA and C3 deposits at the basement membrane zone (BMZ). In the serum, circulating anti‐BMZ antibodies of both IgG and IgA classes were found. This is the first report of a patient with localized pemphigoid in whom circulating anti‐BMZ antibodies of not only the IgG class, but also of the IgA class were present.
