title: [Bladder squamous metaplasia: report of one case and bibliographic review].
abstract: OBJECTIVE
  We report a new case of squamous metaplasia because of its interest and subtle differential diagnosis with other bladder pathologies.
  
  
  METHODS
  We report the case of a male patient with history of previous neoplasia with an exophytic lesion of the bladder wall discovered on follow-up. Pathological diagnosis after TUR was bladder squamous metaplasia.
  
  
  RESULTS
  Follow-up is performed by ultrasound, cystoscopy, and urine cytology in adherence to clinical guidelines due to the possibility of transformation into squamous cell carcinoma.
  
  
  CONCLUSIONS
  Urothelium is able to develop non neoplastic transformations such as squamous metaplasia. The importance of such transformations depends on proper diagnosis and follow-up due to their ability to transform into a neoplastic process.
