Intraepidermal neutrophilic IgA dermatosis: pemphigus-like IgA deposits.
A case of intraepidermal neutrophilic IgA dermatosis with intercellular IgA deposit in the upper epidermis is reported. Indirect immunofluorescence was negative but immunoelectrophoresis showed a slight increase of IgA. The chemotactic activity of neutrophils was normal. Colchicine controlled the lesions.
