title: [Malignant bilateral pheochromocytoma and von Recklinghausen disease].
abstract: OBJECTIVE
  To review the main features of malignant pheochromocytoma and its relationship to von Recklinghausen's neurofibromatosis.
  
  
  RESULTS
  We report on a case of malignant bilateral pheochromocytoma with hepatic and pulmonary metastasis, associated with von Recklinghausen's neurofibromatosis. Surgery achieved good results and the patient is well seven years postoperatively.
  
  
  CONCLUSIONS
  Approximately 10% of the pheochromocytomas are malignant and treatment is principally by surgery. (131) metaiodobenzylguanidine may be useful in cases with metastasis, residual tumor or local relapse.
