特發性間質性肺炎

特發性間質肺炎（Idiopathic interstitial pneumonia，簡稱IIP），又稱非感染性肺炎（noninfectious pneumonia），屬於一種間質性肺病。該疾病通常侵襲肺間質，有些也會侵襲氣道（例如），IIP可分為七個亞型。

組織學分類
IIP的分類相當複雜，須結合、影像學，以及病理学才能確診。

間質性肺炎可由組織學型態分為下列數種：

其中尋常性間質性肺炎為最常見的一種亞型。

發育
Table 1: Development of the (histologic) idiopathic interstitial pneumonia classification

UIP=usual interstitial pneumonia; DAD=diffuse alveolar damage; NSIP=non-specific interstitial pneumonia; DIP=desquamative interstitial pneumonia; RB=respiratory bronchiolitis; BIP=bronchiolitis obliterans interstitial pneumonia; OP=organizing pneumonia; LIP=lymphoid interstitial pneumonia; LPD= (not considered a diffuse lung disease); GIP=giant cell interstitial pneumonia; HMF=heavy metal fibrosis, no longer grouped with diffuse lung disease

Lymphoid interstitial pneumonia was originally included in this category, then excluded, then included again.
