title: An unusual case of cancer of the urachal remnant following repair of bladder exstrophy.
abstract: BACKGROUND
  We report the first case of cancer of the urachal remnant following repair of bladder exstrophy, in a renal transplant recipient.
  
  
  METHODS
  A retrospective review of this clinical case and the associated literature were performed.
  
  
  CONCLUSIONS
  This unusual case highlights two very rare entities. Bladder exstrophy has an incidence of 1 in 50,000 newborns, whereas urachal cancer accounts for less than 1% of all bladder tumours.
