World's largest hand

24-year-old macrodactyly patient Liu Hua, from Jiangsu, China, was recognized in 2007 as the man with the world's largest hand. He was born with a left thumb, index and middle finger much larger than normal, which grew dramatically together with his arm as he grew older and has had a serious impact on his work and day-to-day life.

When Liu was hospitalized in Shanghai in July 2007, his left thumb measured 26 centimeters, his index finger was 30cm and his middle finger 15cm. The overall weight of his left arm was about 10 kilograms. Surgeons ended up making a seven-hour operation to reduce the size of Liu's fingers and thumb, removing 5.1kg of flesh and bone in the procedure. (Link)
