The first reports dates back to second half of the 19th century, the etiological bases could not been ascertained yet. They are mainly classified as true or pseudo-tails.
MATERIAL and METHODS: Five cases with human tails were diagnosed and managed in our hospital between 2010 and 2014. Their demographic and lesion characteristics are presented.
RESULTS: Three of the 5 cases were male patients. The ages ranged between 1 day and 50 years at the time of diagnosis. The patients were diagnosed basically by the external appearance of the lesions without neurological deficits. Detailed examination revealed several associated lesions: two dermal sinus tracts, one tethered spinal cord and one club-foot in one-day preemie. Two patients had true and 3 had pseudo-tails. Four of them underwent surgery but the last one did not accept surgery. Surgery consisted of simple excision of the lesion in 2 patients with true tails and excision and removal of dermal sinus tract and untethering when necessary in the other 2 pseudo-tails.
CONCLUSION: The presented study indicated that true human tails are simple skin appendages without any associated spinal anomalies. However, pseudo-tails are potentially complex lesions with a high risk of spinal dysraphisms; warranting further diagnostic work-up and more extensive surgical technique if necessary. The key to managing human tails is making a clear distinction between true tails and pseudo-tails.
