Living with Junctional epidermolysis bullosa inversa

A rare form of junctional epidermolysis bullosa with blisters in skin folds, groin, and the esophagus, present from birth.

Understanding Junctional epidermolysis bullosa inversa

Junctional epidermolysis bullosa inversa is a rare intermediate form with blistering that is mostly in skin folds and certain body areas.

Blisters and erosions are present from birth and are limited to skin folds, the esophagus, groin, and perineum. Blistering is usually severe, and healing can leave thin scars and tiny white bumps called milia. Nails, teeth, mouth, esophagus, and vagina can also be affected. It is noticed in newborns and infants.

Signs & symptoms

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

  • Blistering skin
  • Fragile skin
  • Thin, sunken scars (atrophic scars)
  • Poorly formed nails
  • Weak tooth enamel
  • Dental cavities

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 genetic specialists, gum, teeth and mouth 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.
