Footage has emerged from China of a 36-year-old man with a rare condition that means large tumours continuously grow on his face.

The video, filmed in Yantai, Shandong Province last Sunday, shows the man - named Yang Shaolei - with a swollen face because he suffers from neurofibromatosis.

According to local reports, the left side of Yang's face started to change when he was three-years-old.

He delayed treatment for quite some time because his family couldn't afford the surgery, but in the end he was forced to go under the knife.

Unfortunately, the surgery didn't work and his conditioned worsened at a fast rate.

He's now looking for more treatment but it's baffling doctors because the disease is so rare.
