The label denotes a pathological biological process or mechanism, not a disease entity.

A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are…

The label is process-shaped, but the organ-specific concept may also function as a disorder; manual semantic review is required.

An autosomal recessive disorder characterized by a triad of DEXTROCARDIA; INFERTILITY; and SINUSITIS. The syndrome is caused by mutations of DYNEIN g…

Pathological processes involving any part of the LUNG.

A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends…

Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.
