Extensive keloid formation after pemphigus vulgaris.

Pemphigus vulgaris is an immunobullous disease characterized by intraepidermal blister formation. These blisters eventually rupture, leaving erosions that are slow to heal, often leaving hyperpigmented patches, but no scars. We describe a case of a 67- year-old man with pemphigus vulgaris who suffered severe keloidal scarring after the pemphigus lesions became infected. His keloids were treated with intralesional corticosteroids with some improvement. Pemphigus vulgaris, a process confined to the epidermis, may lead to scarring in predisposed individuals, particularly if infection occurs.
