Since EBA encompasses a broad spectrum of clinical presentations (classical/mechanobullous form, inflammatory type (BP‐like EBA), mucous membrane‐EBA, IgA‐EBA, and Brunsting‐Perry type EBA);22 IL‐4/−13 levels in EBA patients may reflect the inflammatory characteristics that such subtype resembles; and may be elevated, for example, in BP‐like EBA. Here, IL4 is linked to acquired epidermolysis bullosa.
