General Information
Bullous Pemphigoid is a chronic skin disease characterized by blisters. The blisters usually appear on the flexural areas. A small percentage of individuals may also develop blisters in the mouth or down the throat. The disease is mainly seen in elderly individuals in the fifth through seventh decade of life. Intense pruritus usually accompanies the blisters. The exact cause of the disease is unknown but has been linked to factors including genetics, age, epitope spreading, complement activation and chemokines. Treatment is focused on healing the blisters that exists and decrease the formation of new blisters. Therapy is individualized by patient, keeping in mind preexisting conditions and other specific factors. The most commonly used medications include Anti inflammatory medication and immunosuppressant.
