A 66-year-old man was hospitalized with weakness in the right lower extremity. Chest X-ray and CT scan revealed a large mass on the left upper lobe, and a solitary metastatic tumor was concomitantly found on the left parietal lobe by cranial CT. Resection of the brain metastasis, showed choriocarcinoma histologically. The patient had no abnomarity in his testis. After two courses of chemotherapy, the level of human chorionic gonadotropin (βHCG) in his plasma and urine were decreased. Left upper lobectomy with lymph node disection and chest wall resection was performed. However, the patient died 6 months after surgery from spinal, brain and pulmonary metastases. Pulmonary choriocarcinoma in the male is a rare tumor and only 5 cases have been reported in the Japanese literature.
