Lumbosacral and coccygeal skin covered appendages are a rare malformation, considered human-tails.

Case report

The authors describe the case of a full term newborn girl with lumbar skin appendage and a normal neurologic examination. The magnetic resonance of the spine revealed a dermal sinus continuous with the skin appendage and with extension into to the spinal canal. Due to the infection risk, a surgery was performed on the third day of life, with dermal sinus ligation and appendage removal. At 12 months of follow-up the girl has a normal neurologic examination.


With the description of this case the authors aim to emphasize that although rare, lumbar skin appendages can be associated with spinal dysraphism and other lesions, requiring extensive work-up and long-term surveillance.

Dermal sinus
Spinal dysraphism

Los apéndices humanos lumbosacros y coccígeos recubiertos de piel son malformaciones raras, consideradas colas humanas.

Caso clínico

Describimos el caso de una niña recién nacida a término, con un apéndice cutáneo lumbar y con una exploración neurológica normal. La resonancia magnética lumbosacra demostró un seno dérmico contiguo al apéndice cutáneo con extensión al canal vertebral. Dado el riesgo de infección, fue operada al tercer día de vida realizándose ligación del seno dérmico y resección del apéndice cutáneo. Pasados 12 meses la niña continúa presentando un examen neurológico normal.


Con la descripción de este caso los autores pretenden realzar que, aunque raros, los apéndices cutáneos lumbares suelen asociarse a disrafismos espinales. Precisan, por ello, un estudio exhaustivo y seguimiento a largo plazo.
