Abstract
Background: Bullous pemphigoid is an autoimmune bullous disease that frequently affects a large skin surface area, but it can also present in localized areas. It has been hypothesized that bullous pemphigoid affects the systemic functioning of different organs because inflammatory cells and cytokines circulate throughout numerous organs. Results: Recent clinical and experimental studies have revealed an association between bullous pemphigoid and systemic organ disorders. To avoid the emergence of systemic organ diseases, the significance of systemic treatment in cases of severe bullous pemphigoid should be emphasized. Conclusions: Here, we discuss the specific molecular processes underlying typical systemic organ inflammatory diseases associated with bullous pemphigoids.
