title: [A clinical study of so-called rare pulmonary tumors].
abstract: Six so-called rare pulmonary tumors, resected at the hospital are reported. Histologically there were pulmonary blastoma, pulmonary adenocarcinoma of fetal lung type, alveolar soft part sarcoma, oncocytic carcinoid tumor, hemangioendothelioma, and leiomyoma in each one case. The represented about 1.5% of all resected lung tumors. The age of these patients ranged from 28 to 67 years old, and all were females. Two patients experienced hemosuputum, but the others have no clinical symptoms. All the patients showed relatively well circumscribed mass shadows on chest X-ray films, but none could have accurate diagnosis by preoperative examinations. One patient with alveolar soft part sarcoma died of brain metastasis 18 months after the resection, however, the other 5 patients remained well from 2 year 7 months to 11 years after the surgery.
