Abnormal sputum

Definition

This category includes the abnormalities of quantity, colour and odor in sputum which may suggest an aetiology. Patients with chronic bronchitis typically expectorate small quantities of mucoid yellow material. A foul or fetid odor should suggest infection from anaerobic organisms, usually in cases of lung abscess. Occasionally, greatly excessive amounts of sputum or "bronchorrhoea" is associated with bronchioloalveolar carcinoma.
