What diseases are associated with blisters?

There are several different categories of autoimmune blistering diseases including pemphigus, pemphigoid, IgA-mediated dermatoses and epidermolysis bullosa acquista. Pemphigus, pemphigoid and IgA-mediated dermatoses can be further broken down into additional subtypes.

What is the difference between pemphigus and pemphigoid?

Pemphigus is characterized by shallow ulcers or fragile blisters that break open quickly. Pemphigoid presents with stronger or “tense” blisters that don’t open easily. Those with pemphigoid are also more likely to have hot, red and itchy hive spots.
