title: [Inverted papilloma of the female urethra].
abstract: OBJECTIVE
  Transitional cell inverted papilloma is an uncommon, generally benign tumor that rarely presents in the lower urinary tract. It is characterized by a typical inverted growth pattern and a layer of normal transitional epithelium. One such case is described herein.
  
  
  METHODS
  We report on a 53-year-old female with transitional cell inverted papilloma of the urethra presenting as postmenopausal metrorrhagia. The lesion was removed surgically.
  
  
  RESULTS
  It was a round-shaped, 1.5 cm diameter, polypoid lesion that was resected. Standard pathological analyses disclosed a trabecular type inverted papilloma.
  
  
  CONCLUSIONS
  Transitional cell inverted papilloma of the female urethra is rare. To date it has only been reported in male patients. An additional case of this tumor type is described in a female patient.
