A girl in China is preparing to undergo surgery to have an extra arm removed from her back.
Ren Xin will have the limb removed by doctors in Beijing next week.
The 11-year-old was born with a third arm on her back. She will have to go through four stages of complicated surgery to have the limb removed.
It has been reported that there have been less than 20 similar cases in China.
Earlier this month doctors in India successfully removed four extra limbs from two-year-old Lakshmi Tatma.
More than 30 doctors worked for 27 hours to remove Lakshmi's limbs.
