Living with Transient bullous dermolysis of the newborn

A rare skin blistering condition seen at birth that usually fades within the first one to two years of life.

Understanding Transient bullous dermolysis of the newborn

Transient bullous dermolysis of the newborn is a rare form of dystrophic epidermolysis bullosa with blisters over the body at birth.

The blistering usually goes away within the first 6 to 24 months of life. It is noticed in the newborn period or infancy.

Signs & symptoms

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

  • Blisters over the body
  • Fragile skin
  • Blisters in the mouth
  • Poorly formed or missing nails
  • Small white bumps (milia)
  • Sunken scars (atrophic scars)

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 and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in COL7A1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    DEBRA of America may keep lists of experts for this condition.
