Usual interstitial pneumonia (UIP) is the most common idiopathic interstitial pneumonia and the underlying histology in cases of idiopathic pulmonary fibrosis. It is a progressive disease with poor prognosis. For a long time, there has been no effective therapy but recent studies show promising response to pirfenidone and nintedanib. Accurate diagnosis is very important, especially for prognosis and transplant referral. This short overview will highlight the pathologic features of UIP, some important underlying causes, natural history, and acute exacerbation.
