In 2002, The American Thoracic Society (ATS) and European Respiratory Society (ERS) published a classification schema recognizing seven idiopathic interstitial pneumonias (llPs) (9) (Table 1). These IIPs have disparate clinical expression and prognosis and will be discussed individually. 

Histological pattern Clinical-radiologic-pathologic diagnosis 

Usual interstitial pneumonia Nonspecific interstitial pneumonia Organizing pneumonia Diffuse alveolar damage Respiratory bronchiolitis Desquamative interstitial pneumonia Lymphocytic interstitial pneumonia Idiopathic pulmonary fibrosis/cryptogenic fibrosing alveolitis Nonspecific interstitial pneumonia (provisional) Cryptogenic organizing pneumonia Acute interstitial pneumonia Respiratory bronchiolitis-associated interstitial lung disease Desquamative interstitial pneumonia Lymphocytic interstitial pneumonia
