Baby girl born with 'extremely rare' 2-inch-long hairy tail surprises doctors

The case of a baby girl born with a rare 2-inch-long hairy tail in Mexico has surprised doctors. The "true tail" had no anomalies or bone structure as is often found in vestigial tails, making this case an extremely rare one.

In a case report titled Human Tail In A Newborn, published in the Journal of Pediatric Surgery, the doctors wrote, "The presence of tails in humans is extremely infrequent."

The girl was born via cesarean section at a rural hospital in Mexico where the doctors discovered the tail which was about 2-inch-long and covered with hair. Photos published with the paper show the cylindrical tail with a tapered tip. While an X-ray revealed no evidence of anomalies or bone structures inside the tail, the baby reportedly cried when doctors poked it with a needle.

"The structure was soft, covered in skin, and fine hair, it could be passively moved with no pain, but showed no spontaneous movement. The baby cried when the structure was pinched with a needle," the paper stated.
