title: [Extra adrenal pheochromocytoma. Report of two cases].
abstract: OBJECTIVE
  To review two cases of extra adrenal pheochromocytoma.
  
  
  METHODS
  We present two cases: a 75-year-old patient with history of high blood pressure and intravesical tumor compatible with urinary bladder paraganglioma, and a 59-year-old patient with a retroperitoneal tumor arising from para-aortic ganglia.
  
  
  RESULTS
  Diagnosis was made by CT scan and transurethral resection in the first case, all posterior extension studies were negative; in the second case retroperitoneal exeresis surgery was performed after CT scan.
  
  
  CONCLUSIONS
  Extra adrenal pheochromocytomas are catecholamine producing tumours, which determines their clinical features; treatment should be surgical. A bibliographic review about this disease is performed.
