39 year old Huang Chuncai is thought to have suffered the world's worst case of neurofibromatosis, that causes benign tumours to grow along nerve endings.

The 39 year old is known as "Chin@’s Elephant Man", has been the subject of medical studies and has been forced to turn down offers to appear in a "freak show".

The 39-year-old has now had four ops to remove the two stone (15kg) tumour, that had taken over his entire face, leaving him unrecognisable.

The extreme condition, which manifest itself when Huang was just four years old, causes tumours to develop repeatedly on his face, to the point where the growth once measured a staggering 15 kilogrammes (33 lbs) in weight.

The man from Yulan village in Hunan Province’s Yongxin County, in Central chin@, had his first surgery in 2007 and underwent three more in the years that followed with the help of donations or pro bono operations.

The procedures helped to reduce what was and still is the record for the world’s biggest facial tumour, but his appearance still stops him from venturing out into public.
