Polymorphic pemphigoid. Is it still worth using this terminology?
The term polymorphic pemphigoid has been used in the literature as a variant of bullous pemphigoid. But this term is imprecise and now obsolete, since patients with linear IgA dermatosis have been reported under this terminology. The patients who develop an atypical subepidermal bullous disease with clinical and histological features of both bullous pemphigoid and dermatitis herpetiformis may actually be classified into three groups: (1) vesicular variant of bullous pemphigoid; (2) linear IgA dermatosis, and (3) mixed subepidermal bullous disease.
