The autoimmune reaction most commonly affects the oral<unk> a in the mouth, causing lesions in the gums (gingiva), known as desquamative gingivitis. More severe cases can also affect areas of<unk><unk>  elsewhere in the body, such as the sinuses, genitals, anus, and cornea. When the cornea of the eye is affected, repeated scarring may result in blindness. Brunsting–Perry cicatricial pemphigoid is a rare variant of<unk>  involving the scalp and the neck without<unk> al involvement. It is proposed by some authors that this be called a variant of epidermolysis bullosa acquisita. Nikolsky's sign (gentle lateral pressure) on unaffected<unk> a or skin raises a bulla. If no lesions are present on examination it may be useful way of demonstrating reduced epithelial adhesion. In contrast, in Pemphigus, the epithelium tends to disintegrate rather than form a bulla. Nikolsky's sign is present in pemphigus and<unk> , but not in bullous pemphigoid.
