title: [Bladder leiomyoma with extramural growth. An infrequent cause of pelvic pain].
abstract: OBJECTIVE
  A case of extravesical leiomyoma that had been incidentally discovered in a patient presenting with unspecific pelvic pain is described.
  
  
  RESULTS
  A 51-year-old male patient consulted for unspecific pelvic pain. Patient evaluation disclosed a well-defined mass. A partial cystectomy was performed. Pathological analysis confirmed the diagnosis of leiomyoma of the bladder.
  
  
  CONCLUSIONS
  Mesenchymal tumors of the urinary bladder are rare and account for 1%-5% of all bladder tumors. Leiomyoma is the most common benign non-epithelial tumor. The symptoms caused by this tumor type is varied, unspecific and in most of the cases depends on its location (intravesical, intramural or extramural). Treatment is by surgery, which achieves excellent results.
