Beyond a consensus classification for idiopathic interstitial pneumonias: progress and controversies

Histopathology. 2009 Jan;54(1):90-103. doi: 10.1111/j.1365-2559.2008.03173.x. Epub 2008 Nov 20.


Histopathological classification schemes provide the underpinnings for separating idiopathic interstitial pneumonias into clinically meaningful groups. An interdisciplinary classification system based on a combination of evidence and expert opinion was published in 2002 and set the stage for controversy in several areas, including not only nomenclature but also the role of surgical lung biopsy and pathologists in diagnosis. We provide a brief overview of the clinical and histological features of the idiopathic interstitial pneumonias, and focus on selected topics of interest that have emerged in recent years.
