title: [Oat cell bladder carcinoma. Report of a case].
abstract: OBJECTIVE
  To report an additional case of small cell (oat cell) carcinoma of the bladder.
  
  
  RESULTS
  A 78-year-old patient who consulted for hematuria is described. A TUR biopsy demonstrated small cell undifferentiated carcinoma. The patient received neoadjuvant chemotherapy and subsequently underwent surgery, but died 6 months postoperatively.
  
  
  CONCLUSIONS
  Regardless of the treatment utilized, this tumor type maintains its aggressive behaviour and can be associated with other carcinomatous components (papillary transitional cell carcinoma and carcinoma in situ). However, after treatment with CDDP + VP-16 and partial cystectomy, our patient was asymptomatic for 5 months.
