title: [Bladder hemangioma after radiotherapy].
abstract: OBJECTIVE
  Bladder hemangiomas are exceptional benign tumours representing 0.6% bladder tumours. Most times they present as solitary, unique lesions; radiological signs are very similar to urothelial neoplasias making differential diagnosis or at least diagnostic suspicions very difficult due to its low incidence. We perform a bibliographic review and comment on its clinical and pathological characteristics, as well as on diagnostic methods and latest modifications in therapy.
  
  
  METHODS
  We present a case of bladder haemangioma secondary to pelvic radiotherapy, being this presentation unique among approximately 100 cases described in the literature.
  
  
  RESULTS
  From cystoscopy we suspected the lesion could be an endothelial neoplasia based on its vascular appearance. We performed transurethral resection and electrocoagulation of the lesion because it was small and unique. Pathology report confirmed it was a bladder hemangioma secondary to radiotherapy, being this an exceptional presentation. There has been no relapse up to date.
  
  
  CONCLUSIONS
  We think that resection and electrocoagulation of unique, solitary bladder hemangiomas is a therapeutic option to be taken into consideration in the management of this kind of benign tumours.
