The different types of pemphigus are diagnosed based on the location of the blisters. They include:

Pemphigus vulgaris

Pemphigus vulgaris is the most common type of pemphigus in the Unites States. Blisters usually first appear in the mouth. The blisters don’t itch. They can be painful. Blisters may then appear on the skin and sometimes on the genitals.

Pemphigus foliaceus

Pemphigus foliaceus doesn’t cause blisters in the mouth. The blisters first appear on the face and scalp. Blisters then appear on the chest and back. The blisters are usually itchy and painless.

Pemphigus vegetans

Pemphigus vegetans causes blisters that appear on the groin, under the arms, and on the feet.

Paraneoplastic pemphigus

A very rare type of pemphigus that occurs in people with some cancers is called paraneoplastic pemphigus. The blisters and sores may appear in the mouth, on the lips, and on the skin. This type may also cause scars on the eyelids and eyes. It can also cause lung problems.
