title: Lichen planus pemphigoides: identification of 180 kd hemidesmosome antigen.
abstract: We describe a man with lichen planus pemphigoides. Direct immunofluorescence studies of peribullous skin showed linear deposition of IgG and C3 in the basement membrane zone. Indirect immunofluorescence studies disclosed circulating anti-basement membrane zone antibodies. Immunoelectron microscopy demonstrated binding of antibodies to the hemidesmosomes and lamina lucida. The patient's serum defined only the minor bullous pemphigoid antigen with a molecular weight of 180 kd. These findings suggest the coexistence of lichen planus and bullous pemphigoid in lichen planus pemphigoides.
