[The case of a person who was revealed by adrenal metastasis of pulmonary pleomorphic carcinoma].

We report a case of fifties man. He admitted to our hospital due to a hypochondralgia. Computed tomography revealed a tumor of right adrenal gland and a tumor of upper lobe of the right lung. Adrenal tumor had rapidly increased, so we performed adrenectomy. At first adrenal tumor was diagnosed as primary adrenal cancer because its histological findings did not coincide with those of common histologic types of lung cancer. As there were possibilities that one of adrenal or lung tumor was primary and the other was metastatic or both of the two were double primary, we performed right upper lobectomy. Lung tumor was diagnosed as primary pleomorphic carcinoma containing spindle-shaped tumor cells and adenocarcinoma, and then the diagnosis of adrenal tumor was corrected as metastasis of lung cancer. Two months after the lung operation, cervical lymph node swelling, metastasis of stomach and local recurrence of adrenal tumor appeared. After he underwent six courses of systemic chemotherapy of carboplatin and paclitaxel, a clinical complete response was obtained and no recurrence is observed for 4 years.
