title: Hamartoma of the urinary bladder.
abstract: BACKGROUND
  Hamartomas of the urinary bladder are extremely rare. We report on a case in a 58-year-old female who presented with the chief complaint of pain on urination.
  
  
  RESULTS
  Cystoscopy revealed a solid tumor on the left posterior wall of the bladder. Transurethral resection of the tumor failed to provide a definitive pathological diagnosis of the tumor. Thus, we performed partial cystectomy. The pathological diagnosis was hamartoma arising from the urinary bladder.
  
  
  CONCLUSIONS
  This is the ninth case diagnosed as urinary bladder hamartoma to be reported in the literature.
