Infant in Brazil Emerges with 12-CM Long Authentic Human Tail Appendage

In Brazil, a premature baby boy was born with a rare 12-centimeter-long "true" human tail. This extraordinary case is detailed in the Journal of Pediatric Case Reports. The infant, shielded by anonymity in the report, exhibited jaundice and a fusiform structure, measuring roughly 4 centimeters in its widest diameter, attached to a 12-centimeter fibrous cord in the left paravertebral lumbosacral region. In simpler terms, a tail.

No additional complications were found during the child's examination, which also revealed no other systemic aberrations.

Human tails can be categorized as "true" or "pseudo-tails." While pseudotails are essentially comprised of adipose or cartilaginous tissue with bone components, true human tails remain uncommon, with approximately 40 cases reported in scientific literature. These are embryonic tails that persist until birth, as they normally get absorbed by white blood cells between 6 and 12 weeks of fetal development.

In instances like this, the tail persists despite the lack of absorption by white blood cells. Removal of the tail, performed without incident in this case, may involve muscle tissue, capable of twitching or even curling in some cases.

Initially, doctors investigated potential underlying conditions in the infant. Given the ectodermal connection between the skin and the central nervous system, it is crucial for pediatricians and pediatric surgeons to investigate any signs of hidden spinal dysraphism in patients sporting skin lesions, as they may represent the sole noticeable abnormality. Early detection can prevent progression to severe neurological alterations.

Spina bifida is frequently associated with true tails, but this particular baby was found to be free of other related conditions. The team, however, did not elucidate the cause of the tail. The mother was treated with first-generation cephalosporin for a urinary tract infection and continued smoking 10 cigarettes each day throughout her pregnancy. Following the tail's removal, the infant displayed no further issues and remains in perfect health.

Infants born with true human tails, or caudal appendages, are generally associated with underlying spinal or neural tube defects, potentially leading to various complications and health issues. These conditions can result in mobility challenges, hydrocephalus, and bowel and bladder dysfunction. The presence of a tail may indicate more extensive underlying spinal cord or congenital abnormalities, necessitating thorough medical evaluation. Caudal Appendage Syndrome involves a selection of congenital anomalies, including spinal dysraphism, which can precipitate neurological and orthopedic complications.

While prenatal factors like medication use or smoking have not been directly linked to true human tails, they can increase the risk of congenital abnormalities generally. However, specific research linking these factors directly to human tails remains limited.

1. The persistence of the tail in the infant, despite a lack of absorption by white blood cells, highlights an evolutionary anomaly in health-and-wellness, as true human tails are usually absorbed during fetal development.
2. The medical-conditions associated with true human tails can be severe, leading to mobility challenges, hydrocephalus, and bowel and bladder dysfunction, emphasizing the importance of thorough investigation and early detection in cases of caudal appendages.
3. While prenatal factors such as medication use or smoking may increase the risk of congenital abnormalities, there is limited scientific evidence directly linking these factors to the occurrence of true human tails, indicating the need for further study in the field of science and evolution.
