A three-year-old boy once cruelly dubbed 'Mickey Mouse' over giant 'ears' caused by treatment for a rare skin condition has shown off his amazing recovery.

The youngster, named only as Qibao, was born in Fujian province, southern China, with several giant, dark-coloured moles covering his skull.

The condition, medically known as congenital naevus, is primarily caused by an abnormal overgrowth of pigment-producing cells in the skin that can affect not only a child's appearance, but also their mental well-being and overall quality of life.

Surgeons in Shanghai told his family they could remove them but said little Qibao would have to have his skin stretched before the the surgery so they could cover the gaps.

Pre-operation video footage shared on social media by Qibao's family shows the large balloon-like newly-grown skin on both sides of his head that triggered his heartbreaking nickname.
