Desquamative interstitial pneumonitis | definition of desquamative interstitial pneumonitis by Medical dictionary
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.
Most patients are smokers and adults; DIP rarely occurs in children, in whom it has a worse prognosis.
Better prognosis and response to steroids than UIP (in adults).
Bilateral ground-glass opacification.
Smoking (RBILD), amiodarone therapy, eosinophilic pneumonia, pulmonary alveolar proteinosis.
desquamative interstitial pneumonitis A nonspecific interstitial pulmonary reaction of adults; DIP is often idiopathic but may be associated with inhalation of inorganic particles Radiology Bilateral ground-glass opacifications Treatment Corticosteroids. See Diffuse alveolar damage.
