Bullous pemphigoid usually appears on the belly, chest, arms, legs, groin, or armpits. It may occur in the mouth as sores. It most commonly affects people older than age 60.
Symptoms include fluid-filled blisters that are often located along creases in the skin. Affected skin may be itchy.
Steroid pills and topical steroid creams and ointments can help the skin heal and relieve itching.
