title: [Polypoid cystitis, isolated lesion with a unique presentation].
abstract: OBJECTIVE
  To report on an uncommon case of polypoid cystitis.
  
  
  RESULTS
  The patient had consulted because urinary stream was suddenly interrupted due to a mass protruding into the urethral meatus. The US, IVP, cystoscopic and pathological findings are documented. The literature on polypoid cystitis is briefly reviewed with special reference to its forms of presentation and the pathological findings which permit making the differential diagnosis from other pathologies, the most important being transitional cell papillary carcinoma.
  
  
  CONCLUSIONS
  An uncommon case of cystitis is described, which emphasizes the varied forms of presentation of this condition and the need to distinguish this lesion from other pathologies, particularly bladder carcinoma.
