Two years later, the doctors report the boy is doing so well that he doesn't need any medication, is back in school and even playing soccer.
"We were forced to do something dramatic because this kid was dying," said Dr. Michele De Luca of the University of Modena in Italy, who got a call for help from the German doctors treating the boy.
The boy, then 7, was hospitalized in June 2015 with blisters on his limbs, back and elsewhere. He quickly lost about 60 percent of the outer layer of his skin and was put into an induced coma to spare him further suffering. Doctors at Children's Hospital at Ruhr University in Bochum, Germany, tried skin grafts from his father and donor skin, but all failed.
