Epidermolysis Bullosa Acquisita Associated With Relapsing Polychondritis: An Association With Eosinophilia?

Epidermolysis bullosa acquisita is a blistering disorder that has been associated with other autoimmune diseases. It has not previously been associated with relapsing polychondritis (RPC). RPC is an autoimmune disorder that frequently displays peripheral eosinophilia. The eosinophil has been implicated in mediation of tissue damage and bullae formation. RPC should be added to the list of diseases seen in association with EBA.
