非特异性间质性肺炎
非特异性间质性肺炎（Non-specific interstitial pneumonia，简称NSIP）属于一种特发性间质性肺炎。
症状
病因
目前认为属于一种自体免疫有关，可能为未分化型结缔组织疾病的并发症[2]。
分类
NSIP可依病理切片分为细胞性及纤维性两种，两种以预后不同。细胞性的镜检会显示慢性发炎但纤维化较少的情形；纤维性则会显示间质性纤维化，且发炎状态不一。在其他种类的特发性肺炎一般有一个明显的点状纤维化区域，但在NSIP中没有这种情形，一般为一整片的纤维化[3]。
预后
纤维性NSIP的五年存活率约于 86% 至 92%之间，细胞性则为 100% 。大体来说NSIP的预后较寻常性间质性肺炎（UIP）为佳[4]。
