Curschmann spirals in sputum: mechanism of bronchiole mucoprotein cast formation, microscopic appearance in bronchial asthma and COPD.
Curschmann spirals in a sputum sample.
Curschmann spirals are twisted mucoprotein structures formed in small bronchi due to hypersecretion of mucus and impaired clearance. They are more common in chronic inflammatory diseases of the respiratory tract (e.g., bronchial asthma, chronic bronchitis).
