"Over the years many attempts have been made to reach a consensus on classification of the idiopathic interstitial pneumonias (IIPs). This imposed a great deal of confusion and difficulty not only for clinicians and radiologists but also medical students. The widely accepted classification was developed by the American Thoracic Society (ATS) and the European Respiratory Society (ERS) in 2002 and revised in 2013. The initial classification was mainly based on the histologic findings and divided IIPs into seven subtypes:"
"respiratory bronchiolitis–associated interstitial lung disease (RB-ILD)"
"smoking related IIPs: respiratory bronchiolitis–associated interstitial lung disease and desquamative interstitial pneumonia"
"respiratory bronchiolitis–associated interstitial lung disease (RB-ILD)"
