When he was yet nine years of age, Yang Jianbin noticed that his birthmark was actually growing in size. The dark birthmark was on the right side of his back.
The 37-year-old native of Shanxi Province, China admitted that by age 12, the mark has actually grown into the size of a fist. That was the time that he sought medical help and so a surgery was done to remove it.
This, however, wasn’t the end of the problem for Yang. Eventually, it began growing once more and a recent check up confirmed that it has already increased to 110kg.
Chen Minliang, the chief surgeon, said that Yang’s condition is called Neurofibromatosis – a genetic problem that affects the cell tissue’s normal growth and development. She, however was quick to add that this was the worst case they’ve ever encountered.
“We have seen neurofibromatosis patients before,” said Chen “but this is the biggest nerve tumour we ever saw.” During his stay at the hospital, Yang had to occupy two hospital beds because of the huge tumor. Fortunately, the surgery was a success, although it took 16 hours for the 9 doctors to remove it.
