2 former pediatric leukemia patients have unexpected reunion at Philadelphia medical school
Dawson Nailor was at an event for new students at the Philadelphia College of Osteopathic Medicine when he saw a woman who looked familiar. Ellie Koerner did know him, in fact, because they were both patients being treated for acute lymphoblastic leukemia at Children's Hospital of Philadelphia, when they were both 4 years old. CBS News' David Begnaud reports.
