Newborn with tail - a genetic throwback.

The birth of a child with a caudal appendage resembling a tail generates an unusual interest and anxiety. True human tail is a rare event; less than 40 cases have been reported in the literature so far. It is defined as a caudal, vestigial, midline protrusion of muscle and adipose tissue with skin covering. We are reporting a case of true tail in a baby, a rare event in human.
