title: Incomplete duplication of a lower extremity (polymelia): a case report.
abstract: BACKGROUND
  Polymelia, or congenital duplication of a limb, is an extremely rare entity in humans, with few cases reported in the literature.
  
  
  METHODS
  We present the case of a six-month-old Hispanic boy born with a lower limb bud on the left posterior thigh.
  
  
  CONCLUSIONS
  The infant had a favorable outcome and evolution after surgical treatment of his supernumerary limb, with no after-effects or impairment whatsoever.
