title: [Isolated primary hyperaldosteronism caused by adrenocortical carcinoma].
abstract: OBJECTIVE
  To report a case of adrenocortical carcinoma and primary aldosteronism as the sole endocrine manifestation.
  
  
  RESULTS
  A 39-year-old male with adrenocortical carcinoma and primary aldosteronism is presented. Following complete hormonal and radiological evaluation, right adrenalectomy and nephrectomy were performed (pT2pN0M0, stage II). Blood pressure, serum potassium and aldosterone levels returned to normal. The patient received adjuvant therapy with carboplatin and etoposide. After 15 months' disease-free interval, lung metastasis was diagnosed, without evidence of local recurrence until 5 months later, when hypertension and primary hyperaldosteronism reappeared. There were no other endocrine disorders. Treatment with spironolactone, 5-FU and adriamycin was instituted with no tumor response and the patient died 3 years later from complications of endobronchial metastasis.
  
  
  CONCLUSIONS
  Adrenocortical carcinoma with isolated primary hyperaldosteronism is uncommon and consequently there is no wide experience in regard to its diagnosis and treatment. Although randomized studies are not available, adjuvant therapy using other agents instead of mitotane (o,p-DDD), such as the combination of cisplatin and etoposide (VP-16), seems reasonable in the locally advanced stages. Mitotane may be useful when hypercortisolism is present, but its efficacy as an antitumor agent has been controversial.
