Understanding Benign mucous membrane pemphigoid

Benign mucous membrane pemphigoid is a rare, chronic, blistering and scarring disease that affects the lining of the mouth and eyes.

Other moist linings can also be affected, such as the nose and throat, voice box, genitals, rectum, and esophagus. Scarring of the eye lining may lead to loss of vision. It is considered an autoimmune disease, where the immune system makes antibodies against parts of the body's own skin and lining tissue. It can start at a variety of ages.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Blisters inside the mouth
  • Inflamed gums (gingivitis)
  • Scarring of the skin
  • Blistering of the skin
  • Cloudiness of the clear front of the eye (cornea)

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

    Specialists who may be involved include eye disease specialists and skin, hair, and nail specialists.

  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.
