105 outpatients with hemoptysis and 170 patients with hemoptysis examined by fiberoptic bronchoscopy were studied. Most of the causes of hemoptysis were upper respiratory infection, primary lung cancer, chronic bronchitis, lung tuberculosis, bronchiectasis and valvular heart disease. 34 cases out of 92 cases of lung cancer were accompanied by hemoptysis. There was no difference in terms of incidence of hemoptysis between squamous cell carcinoma and adenocarcinoma. Four cases of lung cancer with lethal massive hemoptysis were reviewed. The causes were bronchopulmonary fistula, cardiac involvement, pulmonary artery involvement and massive infiltration of the bronchial wall. Four cases of non-malignant diseases with lethal massive hemoptysis were also reviewed. They consisted of embolectomy for pulmonary embolism, aortitis syndrome, acquired valvular disease and pseudoaneurysm of the descending aorta. In the case of an acquired valvular disease, striking bronchial venous engorgement was recognized by bronchoscopy and necropsy. Lethal massive hemoptysis in this case was thought to be due to rupture of the bronchial vein.
