The girl born with a TAIL: extremely rare defect 6 cm long is ‘covered with hair and skin’

  • The extremely rare phenomenon has been recorded less than 200 times
  • The unnamed child was born via cesarean section to healthy parents in their twenties
  • Doctors quickly spotted a 5.7 cm long tail that was ‘covered with skin and fine hair’

In Mexico, a girl was born with a tail.

The extremely rare phenomenon has been recorded less than 200 times.

The unidentified baby was born via cesarean section at a rural hospital in Nuevo Leon to healthy parents in their late 20s.

But doctors soon spotted a 5.7-cm-long (2.2 in) tail that was “soft,” “covered with skin and fine hair,” and had a “pointy” tip.

Scans (pictured) showed that the tail was not the result of a spinal problem, such as spinal dysraphy - a condition in which the spider does not form properly and can cause a tail-like growth on the underside of the spine

Shortly after she gave birth, doctors quickly spotted the tail.  They said it stuck out at the end of her tailbone with the base slightly to the left.  It varied between 3mm and 5mm in diameter, tapering towards the 'pointed' tip

What is a Human Tail?

Human tails are split into two categories.

“Psudotails” are growths that resemble a tail, but are caused by spinal problems or tumors.

Meanwhile, “true tails” contain muscles, blood vessels and nerves, but no bones – similar to those found in animals.

It is thought to arise from the embryonic tail that all babies develop in the womb.

For almost all babies, it is absorbed back into the body to form the tailbone.

But it is thought to develop into a tail in extremely rare cases – with fewer than 200 cases ever reported.

They are generally not noticed until after a baby is born and doctors don’t know what causes them – with only one example where they run in families.

Human ancestors, in addition to our ape relatives, lost our tails when we diverged from apes about 20 million years ago.

Human tails are considered sacred and worshiped in some religions and cultures.

In detail of the incident in Journal of Pediatric Surgery Case Reports, doctors led by Dr. Josue Rueda believe it is Mexico’s first-ever case.

The doctors said the baby was born to term and there were no complications during the pregnancy.

Her parents already had a healthy son.

But shortly after she gave birth, doctors soon spotted the tail.

They said it stuck out at the end of her tailbone with the base slightly to the left. It varied between 3mm and 5mm in diameter, tapering towards the ‘pointed’ tip.

The doctors wrote: ‘The structure was soft, covered with skin and fine hair, it could be moved passively without pain, but showed no spontaneous movement. The baby cried when the structure was pinched with a needle.”

The newborn was otherwise healthy, with brain, heart, hearing and urine tests showing normal results.

It is believed to arise from the embryonic tail that all babies develop in the womb, but is usually reabsorbed into the body to form the tailbone.

Scans revealed that the tail was not the result of a spinal problem, such as spinal dysraphy – a condition in which the spider does not form properly and can cause a tail-like growth on the underside of the spine.

Doctors discharged the baby and reassessed her when she was two months old. She was a healthy weight and height and the tail had grown 0.8 cm.

Surgeons removed the tail in a minor operation performed under local anesthesia.

The patient was discharged the same day and experienced no complications.

Closer analysis of the tail revealed that it contained soft tissue, arteries and veins, and nerve bundles.

The team noted that human “true tails” are “extremely rare,” with just 195 cases identified in 2017, the longest of which is 20 cm (7.9 in).

They are most often found in boys and one in 17 babies with tails also suffer from growth disorders in the brain or skull.
