The abnormal accumulation of inflammatory cells in lung tissue may lead to any one of several disorders with similar signs and symptoms. As white blood cells and protein-rich plasma build up in the air sacs of the lungs (alveoli), inflammation is generated. The inflammatory process, if it lasts long enough, may harden the fluid and the resultant firm, fibrous substance (scarring) may replace the lung tissue. If the scarring is extensive, the air sacs may be destroyed over time and the resultant space replaced by cysts.
The American Thoracic Society and the European Respiratory Society jointly studied the interstitial pneumonias during 2001 and issued a Multidisciplinary Consensus Classification of the Idiopathic Interstitial Pneumonias. This consensus statement was intended to replace several older classification schemes that had led to a confusion of names and syndromes.
Participants agreed that the Idiopathic Interstitial Pneumonias (IIPs) comprise a number of clinical entities that are each rare and sufficiently different from one another to be considered as distinct disorders. This report follows the joint ARS/ERS classification.
