Herpetiform pemphigus is a rare superficial pemphigus disease characterized by severe intractable pruritus with erythematous or urticarial plaques and vesicles organized in a herpetiform pattern. Mucosae are generally spared. Eosinophilia in peripheral blood and low titers of circulating autoantibodies are observed in many cases. Histologically, minimal or no apparent acantholysis is associated.
