title: [Diagnosis and treatment of pheochromocytoma].
abstract: OBJECTIVE
  To improve the diagnosis and treatment of pheochromocytoma.
  
  
  METHODS
  From 1958 to 1998, 286 cases of pheochromocytoma, confirmed by open surgery and pathology, were retrospectively analyzed.
  
  
  RESULTS
  The tumors in the adrenal gland were seen in 220 cases, and in the external adrenal gland in 66. Of 29 cases of malignant pheochromocytomas, 7 were noted in the adrenal and 22 in the external adrenal gland. 19 cases showed stationary pheochromocytomas without clinical features. Total resections were performed in 281 cases.
  
  
  CONCLUSIONS
  The operative mortality could be reduced by the prevention of potential myocardiopathy. The diagnosis of malignant pheochromocytoma should depend upon the long-term follow up.
