When Kevin Lopez opens the door to his Greenbelt, Md., apartment to greet a visitor he's never before met, he initially conceals his right hand.
"I'm self-conscious, definitely, about my right hand," he says. But eventually Lopez relaxes.
"I was born like this," he says. "As you can see, I don't have any fingers." It bothers the 20-year-old enough that he has volunteered to do something drastic: to have his right hand removed and replaced with another person's hand via surgery.
