[Lung sarcoidosis: Clinical features and therapeutic issues].

Sarcoidosis is a granulomatous disease of unknown cause. This proteiform disease is characterized by an almost constant and often predominant lung involvement. The natural history of disease is difficult to predict at presentation.

Nonspecific interstitial pneumonia: survival is influenced by the underlying cause.

Idiopathic, nonspecific interstitial pneumonia (NSIP) is most often associated with various clinical disorders, including connective tissue diseases (CTDs) and chronic hypersensitivity pneumonitis (cHP). Emerging evidence also suggests that "idiopathic" NSIP may be the lung manifestation of undifferentiated CTD (UCTD). However, whether or not NSIP outcome is influenced by the underlying cause remains uncertain.
