Haemoptysis is defined as the expectoration of blood or blood-streaked sputum from the lower respiratory tract. The term derives from the ancient Greek words haima, meaning blood, and ptysis, meaning spitting. The presence of haemoptysis, even in the case of minor events, is a frightening symptom for the patient.
