desquamative interstitial pneumonitis

desquamative interstitial pneumonia

A generally mild, nonspecific interstitial pulmonary reaction that is a double misnomer—as it is neither desquamative nor interstitial—which is characterised by diffuse deposition of haemosiderotic macrophages. DIP is often idiopathic but may be associated with inhalation of inorganic dusts.
Demographics
Most patients are smokers and adults; DIP rarely occurs in children, in whom it has a worse prognosis.
Prognosis
Better prognosis and response to steroids than UIP (in adults).
Imaging
Bilateral ground-glass opacification.

DiffDx
Smoking (RBILD), amiodarone therapy, eosinophilic pneumonia, pulmonary alveolar proteinosis.
Management
Corticosteroids.
