Some factors affecting prognosis in pemphigus vulgaris and pemphigoid.

The records of twenty-eight patients dying with pemphigus vulgaris, and forty-two with pemphigoid, have been examined for factors affecting the length of their survival. Age at onset of the disease is important, old patients dying significantly more quickly than young ones. A short pre-treatment phase signifies a fulminating course in pemphigus vulgaris but not in pemphigoid.
