Respiratory bronchiolitis interstitial lung disease refers to a form of idiopathic interstitial pneumonia associated with smoking.
It is a histological finding, not a pathological description. When associated with disease, it is known as "Respiratory bronchiolitis-associated interstitial lung disease" or "RB-ILD".
The appearance is similar to desquamative interstitial pneumonia, and some have suggested that the two conditions are caused by the same processes.
