Autoimmune blistering diseases are a group of disorders where the immune system mistakenly attacks the skin and mucous membranes, leading to the formation of blisters. Common types include pemphigus vulgaris and bullous pemphigoid, which can cause painful sores and skin damage. These conditions often require medical diagnosis and treatment to manage symptoms and prevent complications. The exact cause of autoimmune blistering diseases is not fully understood, but they can be triggered by factors such as infections, medications, or genetic predispositions. Treatment typically involves immunosuppressive medications to reduce the immune response and promote healing of the affected areas.
