Bullous pemphigoid is a subepidermal blistering skin disease, usually occurred in the elderly. It is an autoimmune disease associated with circulating autoantibodies directed against structural components of hemodesmosome. Rarely, it can involve the esophagus, which can be complicated by upper gastrointestinal hemorrhage. We report a case of bullous pemphigoid with esophageal mucosal desquamation and hemorrhage in patient with chronic renal failure.

Bullous pemphigoid(BP)is an autoimmune blister disease caused by antibodies to the basement membrane zone.It usually exhibits tense bullae in skin and mucous membrane.BP patients can suffer from thrombosis due to hypercoagulation and/or hemorrhage due to the presence of anti-coagulation factors,which may be explained by the eosinophils,antibodies to the coagulation factors,and fibrinolytic system hyperactivity or inhibition.
