Epidermolysis bullosa (EB) is an inherited connective tissue disease causing blisters in the skin and mucosal membranes, with an incidence of 1/50,000. Its severity ranges from mild to lethal. It is caused by a mutation in the integrin α6β4 cell adhesion molecule on either the alpha or beta subunit.
As a result, the skin is extremely fragile. Minor mechanical friction or trauma will separate the layers of the skin and form blisters. People with this condition have an increased risk of cancers of the skin, and many will eventually be diagnosed with it as a complication of the chronic damage done to the skin.
Epidermolysis bullosa refers to a group of inherited disorders that involve the formation of blisters following trivial trauma
