Sarcoid Lung Disease

End-stage pulmonary sarcoidosis

Sarcoid lung disease may result in progressive lung failure, necessitating transplant. There is a debate on whether the scarring is similar to or distinct from that seen in other fibrotic lung disease such as usual interstitial pneumonia (UIP).

In contrast to the honeycombing of UIP, the honeycombing was predominantly central, with prominent bronchiectasis.

The end-stage sarcoid lungs are characterized by a fibrotic and active granulomatous pattern, both of which are very distinct from that seen in UIP.
