**1. Introduction**

Skin blistering diseases are clinically polymorphic large-group disorders and they sometimes may be devastating. These disorders may be classified according to [1] the level of the blister: subcorneal, mid epidermis, suprabasal, subepidermal; [2] the mechanism of blister formation (spongiosis, acantholysis, blistering degeneration, or epidermolysis); and [3] the type of inflammation (neutrophilic, lymphocytic, eosinophilic, mixed) [1]. In this section, pemphigoid group diseases such as bullous pemphigoid, mucous membrane pemphigoid, acquired epidermolysis bullosa, linear IgA bullous dermatosis, and anti p-200 pemphigoid will be explained with a brief introduction to blistering diseases of the skin. The features of subepidermal bullous disorders were summarized in **Table 1**.
