Fibrotic non-specific interstitial pneumonitis

Fibrotic non-specific interstitial pneumonitis is a histological subtype of non-specific interstitial pneumonitis (NSIP). It is considered the more common form 1. This pattern manifests as chronic interstitial inflammation obscured by interstitial fibrosis (with dense collagen), a temporal homogeneous pattern, and occasional focal honeycomb fibrosis 3.

Treatment and prognosis

Corticosteroid can be given but it carries a worse prognosis than the cellular type.
