We read with interest the study by Koga H et al and we believe that in light of recent observations including our data the “desmoglein compensation theory” as a explanation for localization of blisters should be revisited.

Three clinical types of pemphigus have been described, the mucosal dominant, cutaneous and mucocutaneous type.
