Background. The incidence of true pulmonary carcinosarcoma is about 0.1~0.3% of all malignant lung tumors, and it has a tendency to occur in heavy smokers and elderly men. Preoperative diagnosis is very difficult, and there is no established method of treatment. The tumor sizes of true pulmonary carcinosarcoma are generally large and the prognosis is poor. Case. A 54-year-old man was admitted to our hospital because of hemoptysis. Chest radiograph and CT showed a mass of 9.5 cm in diameter in the left lower lobe. A transbronchial lung biopsy did not lead to a definitive diagnosis. However, because the tumor was growing rapidly, we performed surgery. The postoperative pathologic diagnosis was pulmonary carcinosarcoma with adenocarcinoma and chondrosarcoma. Now, at 7 years postoperatively, he is alive without recurrence. Conclusion. We treated a patient with true pulmonary carcinosarcoma, who achieved long-term survival.
