Hemoptysis can happen with lung malignant growth, contaminations, for example, tuberculosis, bronchitis, or pneumonia, and certain cardiovascular conditions.Hemoptysis is coughing up blood from the respiratory tract. Blood come from the respiratory tract such as nose, mouth, throat, the airway passages leading to the lungs, or the lungs. The word "hemoptysis" derived from the Greek "haima," meaning "blood," and "ptysis," which means "a spitting". Hemoptysis is an important symptom that elicits fear in both the patient and physician. Work-up for this symptom should be undertaken immediately unless the problem is both mild and recurrent, in which case a conservative approach may sometimes be preferable.Hemoptysis is the coughing of blood from a source below the glottis. It can range from a small amount of blood-streaked sputum to massive bleeding with life-threatening consequences due to airway obstruction, hypoxemia, and hemodynamic instability.In one study of patients in a UK primary care database, the incidence of hemoptysis was found to be 1 case in 1000 patients per year. Massive hemoptysis occurs in around 5% to 15% of patients presenting with hemoptysis as a chief presenting symptom. The rate of bleeding has been described as the most important factor determining mortality.The initial diagnostic evaluation should aim to differentiate between hematemesis (i.e., the vomiting of blood), pseudohemoptysis (i.e., the coughing of blood from a source other than the lower respiratory tract), and hemoptysis.
