Dystrophic epidermolysis bullosa (DEB) is a rare inherited skin disorder. The skin of those who have DEB is more fragile than normal. Minor injury causes blisters which often leave scars when they heal. DEB can be mild, causing little more than minor inconvenience, but it can also be severe, affecting the mouth, gullet and eyes in addition to the skin. DEB is not an infection, it is not contagious and it is not due to an allergy.
Dystrophic epidermolysis bullosa (DEB) is divided into two major types depending on inheritance pattern: recessive dystrophic epidermolysis bullosa (RDEB) and dominant dystrophic epidermolysis bullosa (DDEB). Each type is further subdivided into multiple clinical subtypes.
DEB is different from the other forms of epidermolysis bullosa (EB), which include epidermolysis bullosa simplex, junctional epidermolysis bullosa and Kindler Syndrome. Individuals who have DEB will not develop one of the other types of epidermolysis bullosa at a later date.
