Discharge of blood from the mouth may be caused by heart disease, carcinoma, hemophilia, arteriosclerosis, vicarious menstruation, hysteria, aneurysm, bleeding gums, or nasal, pharyngeal, or gastric lesion, but the great majority of hemorrhages are from tuberculosis of the lungs.
Stricker1 found 221 of 480 hemorrhages due to tuberculosis, and in 196 more this was probably the cause. Sée1 (1884) says, "Aside from infections diseases, hemophilia, and acute infections of the lungs (pneumonia, abscess, gangrene) we only know of two real causes of hemoptysis—heart disease and pulmonary tuberculosis."
The pathologic conditions preceding hemorrhage vary with the stage of the disease. In early cases it may be due to localized hyperemia in the lung induced by violent or long-continued exercise; or, more likely, due to weakening and erosion of small blood-vessels by the growth of tubercles. Early hemorrhages are always venous; in later stages hemorrhages arise from both the arteries
