What is Epidermolysis bullosa?

Epidermolysis bullosa is a group of rare diseases that cause fragile, blistering skin. The blisters may appear in response to minor injury, even from heat, rubbing, scratching or adhesive tape. In severe cases, the blisters may occur inside the body, such as the lining of the mouth or the stomach.

Most types of epidermolysis bullosa are inherited. The condition usually shows up in infancy or early childhood.

Epidermolysis bullosa has no cure, though mild forms may improve with age. Treatment focuses on caring for blisters and preventing new ones.

Symptoms

Epidermolysis bullosa signs and symptoms vary depending on type.

They include:

  • Fragile skin that blisters easily, especially on the hands and feet
  • Nails that are thick or don't form
  • Blisters inside the mouth and throat
  • Thickened skin on the palms and soles of the feet
  • Scalp blistering, scarring and hair loss (scarring alopecia)
  • Dental problems
  • Difficulty swallowing (dysphagia)
  • Itchy, painful skin

Having a family history of epidermolysis bullosa is the major risk factor for developing the disorder.

Complications of epidermolysis bullosa may include:

  • Infection.
  • Sepsis.
  • Constipation.
  • Skin cancer.
