The Indonesian man dubbed "Tree Man" because of massive bark-like warts all over his body is back in the hospital.
Dede, who like many Indonesians goes by one name, underwent a ninth round of surgery Thursday to remove more of the growths, Agence-France Presse reported.
The 38-year-old had extensive treatment last year to remove the fast-growing warts, but the doctor warned they are rapidly growing back.
"No cure for the disease exists yet, so he needs operations every three to four months because the warts keep on growing," said Rachmatdinata, director of Hasan Sadikin Hospital in Bandung city, West Java.
Intense treatment last year allowed Dede to use his hands and move with relative freedom for the first time in years, AFP reported.
Dede has been covered with the bark-like warts for more than 20 years. The growths are believed to be caused by the human papillomavirus (HPV) and began to appear on his skin after he cut his leg when he was just 15-years-old.
