Sultan Kosen, the world's tallest man according to the Guiness book of records, received treatment at the University of Virginia Medical Center. He's also in the record books for having the largest hands (11.22 inches) and largest feet (14.4 inches). Dr. Jason Sheehan (far right) performed radiosurgery to a tumor in Kosen's pituitary gland to stop his excess production of growth hormone. His endocrinologist, Mary Lee Vance, on Kosen's right, placed him on a new medication to help stop his growth. (Photo Credit: University of Virginia)
