A 62-year-old male was admitted with abnormal shadow in chest X-P. CT and other examinations were done, and he was diagnosed left renal cell carcinoma with metastatic lung cancer. He rejected operation and was discharged. We gave him alpha-interferon injection every day. About 5 months later, he complained of fever and dyspnea, and was admitted. On the 10th day after admission, he died suddenly with massive hemoptysis. This hemoptysis was from the pulmonary artery, which was surrounded by tumors and ruptured into the trachea. Pathological diagnosis was double cancer, such a case is very rare with a primary lung cancer (oat cell carcinoma) which has metastasized into a renal cell carcinoma (common type, clear cell subtype).
