Epidermolysis bullosa is an exotic name for what is, in its most severe form, unusual, painful and fatal disease. It is caused by a deficiency of the protein that binds the two skin layers together, creating friction, blisters and open, slow-healing wounds. These blisters and erosions occur Even on internal mucous membranes. The wounds are similar to third degree burns, and children – victims of its most severe form will rarely be older than that – are also more prone to skin cancer. A cure does not exist.
