 ==Non-specific interstitial pneumonia==
 *Abbreviated ''NSIP''.
+{{Main|Non-specific interstitial pneumonia}}
-===General===
-*Better prognosis than [[UIP]].
-*Some radiologists and pathologists don't believe in this entity.
-Associations:<ref name=Ref_WMSP92>{{Ref WMSP|92}}</ref>
-*Connective tissue disease.
-*[[Rheumatoid arthritis]].
-===Gross/Radiology===
-*No honeycombing.
-*Fibrosis usually lower lung zone.
-*Patchy ground glass.
-===Microscopic===
-Features:<ref name=Ref_WMSP92>{{Ref WMSP|92}}</ref>
-*Diffuse fibrosis:
-**Uniform fibrosis (unlike [[UIP]]).
-**"Linear fibrosis" has a good prognosis - should be mentioned in the report.
-***''Linear fibrosis'' = fibrosis that follows alveolar walls + no architectural distortion.
-*+/-Lymphoid nodules - association with collagen vascular disease. (???)
-*+/-Focal [[organizing pneumonia]].
-Notes:
-*Inflammation in NSIP usually more prominent than in UIP.
-*No honeycombing - key difference between UIP and NSIP.
-DDx:
-*Collagen vascular disease.
-*Drug reaction.
-*[[Hypersensitivity pneumonitis]] (extrinic allergic alveolitis).
-*[[Lymphocytic interstitial pneumonia]] (LIP) - much more inflammation.
