Epidermolysis bullosa (ep-ih-dur-MOL-uh-sis buhl-LOE-sah) is a group of rare diseases that cause the skin to blister. The blisters may appear in response to minor injury, heat, or friction from rubbing, scratching or adhesive tape. In severe cases, the blisters may occur inside the body, such as the lining of the mouth or intestines.
Most types of epidermolysis bullosa are inherited. The condition usually shows up in infancy or early childhood. Some people don't develop signs and symptoms until adolescence or early adulthood.
Epidermolysis bullosa has no cure, though mild forms may improve with age. Treatment focuses on addressing the symptoms — such as infection and itching — and preventing pain and wounds. Severe forms may cause serious complications and can be fatal.
