newborn baby born with tail

Hospital successfully removes tail from newborn baby


  • A baby was born in Brazil with a human tail with a ball at the end of it.
  • After ruling out potential neurological involvement, the hospital successfully removed the baby’s tail through surgery.
  • Only approximately 40 cases of real human tails have ever been reported.

The Albert Sabin Children’s Hospital in the city of Fortaleza, Brazil, successfully removed a human tail from a newborn baby boy without complications.

According to the Journal of Pediatric Surgery Case Reports, the baby was born with jaundice and a human tail with a ball at the end of it.



According to the case report, the baby’s mother was previously healthy and did not consume illegal drugs or alcohol. However, she experienced one urinary tract infection during her first trimester, treated with antibiotics, and smoked 10 cigarettes per day during her pregnancy.

The baby was delivered prematurely at 35 weeks with an uncomplicated vaginal delivery, but with jaundice and a tail.

The hospital first performed an ultrasound examination to rule out the possibility of the tail’s neurological involvement. After a negative result, the medical staff performed a successful surgery to remove it.

The authors noted that there have only been approximately 40 reported cases of real human tails. They explained that most humans grow a tail in the womb around the fourth week of gestation. But this tail usually disappears by the eighth week when it morphs into the tailbone or coccyx.

Human tails can be classified into true or pseudo-tails.

A true human tail was described as a persisting remnant of the tail formed in the womb. This is composed of “adipose and connective tissue, blood vessels, muscle and nerve fibers,” while a pseudo-tail is only a protuberance “composed of adipose or cartilaginous tissue and the presence of bone elements.” Pseudo-tails are usually a symptom of a tailbone abnormality or spina bifida.

Our ancestors are believed to have had some form of a tail, but as we evolved as a species, we no longer grew one as there was no more need for a tail.
