Abul Bajandar (L), 26, dubbed "Tree Man" for massive bark-like warts on his hands and feet, sits at Dhaka Medical College Hospital in Dhaka on January 31, 2016. A Bangladeshi autodriver dubbed "Tree Man" for massive bark-like warts on his hands and feet will finally have surgery to remove the growths that first appeared 10 years ago, a hospital said on January 31, 2016. The massive warts, which first started appearing when he was a teenager but began spreading rapidly four years ago, have been diagnosed as epidermodysplasia verruciformis, an extremely rare genetic skin disease that makes the person vulnerable to warts.
