Bullous Pemphigoid Associated with Cerebral Infarction: Hypereosinophilia as a Possible Mechanism

ABSTRACT

Bullous pemphigoid (BP) is an autoimmune skin disease, which manifests as subepidermal blisters with severe itching. BP has been reported to be associated with a higher prevalence of cerebrovascular diseases in population-based studies. However, the mechanism of cerebral infarction from BP has not been elucidated yet. We hereby suggest that the missing link between BP and cerebral infarction may be eosinophil, through a case of a woman with multifocal embolic infarction.
