This is an uncommon autoimmune skin disease in which blisters, bullae, and ulcerative erosions are found on the skin of the trunk, groin, armpits, and abdomen. Collies and Doberman Pinschers appear to be predisposed. This disease also affects the foot pads, and 80 percent of cases ultimately involve the mouth.
Treatment: Treatment is similar to that for pemphigus foliaceus. The outlook for improvement is poor.
