Pan Xianhang

Pan Xianhang was born in Wenling, China with a rare genetic skin disease known as Ichthyosis, after the ancient Greek word for fish.

Most sufferers develop dry scaly skin across part of their body, but Pan's case is more severe. His scales have affected the shape of his eyes, nose, mouth and ears - and they limit the movement of his arms and legs.

The condition also means he's in constant pain and struggles to sleep at night because of the itching. Sufferers are treated with creams, oils and moisturizers, which are designed to hydrate the skin. Liz Dale a spokesperson for the UK-based Ichthyosis Support Group told The Sun: "There is no known cure and treatments for ichthyosis are predominantly keeping the skin moisturized with plenty of emollients i.e. lotions and creams. The skin needs to be moisturized to prevent it from further drying out, which could cause the skin to crack, making it more prone to infection, which may be fatal."
