Abstract

Background
Human tails are rare congenital anomalies protruding from midline of the lumbosacral region covered by skin. Human tails are
classified as true tail and pseudo tail. True tails, also known as vestigial tails are caudal, midline protrusion capable of spontaneous
or reflex motion, consisting of skin covering with a combination of striated muscle, adipose and connective tissue, normal blood
vessels and nerves.
Case Presentation
A 47-days-old-female infant born from 28-years old prime parous women present with cutaneous appendage arising from the sacrococcygeal
region, in the midline, above the intergluteal cleft. The tail-like structure was 9 cm in length, with a diameter between
3 cm and 2 cm in all its length, cylindrical, and pointy towards the end. The structure was soft, covered in skin, it shows spontaneous
movement. The magnetic resonance imaging (MRI) report shows S1-S2 level spinal bifida.
Conclusion
This is a rare case of vestigial human tail with spinal bifida on 47-days old female infant born from prime parous mother through
spontaneous vaginal delivery diagnosed by histopathologic examination.
