(b) Histopathological examination reveals subepidermal cleavage and a rich inflammatory infiltrate dominated by neutrophils. (c) Direct immunofluorescence microscopy analysis of perilesional skin shows linear IgA deposition at the dermo-epidermal junction. (d) Serum IgA-autoantibodies bind to the epidermal side of 1M NaCl-split skin by indirect immunofluorescence microscopy (all magnification 200x).
