How is NSIP Differentiated from Other Interstitial Lung Diseases?
NSIP is differentiated from other interstitial lung diseases primarily by its histological patterns. For instance, UIP is characterized by patchy fibrosis and honeycombing, whereas Organizing Pneumonia (OP) presents with plugs of granulation tissue within the airspaces. The uniformity of inflammation and fibrosis in NSIP is its hallmark feature, which sets it apart from more heterogeneous diseases.
