Living with Pemphigus

A group of rare autoimmune conditions that blister the skin and the moist linings of the mouth, nose, and throat.

Understanding Pemphigus

Pemphigus is a group of rare autoimmune diseases that cause blistering of the skin and mucous membranes.

Mucous membranes are the moist linings of the mouth, nose, throat, eyes, and genitals. Pemphigus can occur at any age but often starts in middle or older age. Different types, such as pemphigus vulgaris and pemphigus foliaceus, are more common in some regions than others.

Signs & symptoms

GARD doesn't list specific symptoms, but the summary describes:

  • Blisters on the skin
  • Blisters on the mouth, nose, throat, eyes, or genitals

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Autoimmune Association and International Pemphigus & Pemphigoid Foundation may keep lists of experts for this condition.

Quick facts

GARD describes pemphigus as an autoimmune disease, which means the immune system attacks the body's own tissue.
