Living with Pretibial dystrophic epidermolysis bullosa

A rare skin condition with fragile skin that blisters easily, mainly on the front of the lower legs.

Understanding Pretibial dystrophic epidermolysis bullosa

Pretibial dystrophic epidermolysis bullosa (DEB-Pt) is a rare form of epidermolysis bullosa, a condition with fragile skin that blisters easily after minor injury or friction.

In this form, blisters and skin sores mainly occur on the front of the lower legs. In some people the feet, hands or nails are affected too. Healing is usually linked to thick scarring. It starts at birth or in infancy.

Signs & symptoms

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

  • Blisters on the front of the lower legs
  • Fragile skin
  • Thick scars after healing
  • Nail changes or missing nails
  • Itching
  • Small white bumps (milia)

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.
