23-year-old Luiz Augusto Márcio Marques stopped growing after undergoing a surgical (外科手术的) procedure to remove a very rare tumor. Today he looks like a 13-year-old boy.

Luiz in Southern Brazil had a perfectly normal life until the age of 7, when he started experiencing painful headaches that began appearing more frequently as time passed. None of the doctors could diagnose (诊断) his condition correctly, and the headaches started affecting his school activity and his daily life. It was only after the boy suffered a seizure that he was taken to the city hospital where the real cause of his headaches was finally revealed.

Doctors told the boy’s aunt that they would have to operate (动手术) on him to remove part of the tumor, or he would die in a matter of days. However, the surgery itself could cause many risks, as the tumor’s location meant that Luiz could lose his ability to walk, talk, or move his eyes and his growth could be affected. In the end, his family decided to take the risk and save the boy’s life.

After the operation, Guto was placed in a glass room where he was monitored around the clock because the doctors wanted to see if he would suffer any seizures or display any unusual symptoms (症状). Luckily, he recovered perfectly, but after performing a series of tests, doctors delivered some grim news. He would most likely stop growing normally at some point. It could be within a year, two, or three, no one could tell for sure. He stopped growing around the time he turned 12, and today, at age 23, he still looks at least a decade younger.

Now 23-year-old Guto is 1.62m tall, weighs about 50kg, and looks no older than 13, but he no longer lets that affect him.
