Pemphigus is a group of rare skin disorders that cause blisters of your skin or mucous membranes, such as in your mouth or on your genitals.
There are two main types: pemphigus vulgaris and pemphigus foliaceus. Pemphigus vulgaris is the most common form. Pemphigus can occur at any age, but often strikes people in middle age or older.
Usually a chronic condition, pemphigus is best controlled by early diagnosis and treatment, which may include medications or treatments similar to those used for severe burns.
