Pemphigus Foliaceus is less severe and less common. Soft blisters typically occur close to the
surface of the skin and when they rupture, they ooze and become crusty,
scaly, and susceptible to infection. Blisters may occur on the scalp, face,
upper chest, and back. The mucous membranes are usually not affected. Small,
horny plugs attached to the undersurface of the affected skin also may be
seen.
