    Abstract:
    Sarcoidosis very rarely progresses towards severe subacute respiratory failure. We report three observations of recent atypical cases of pulmonary sarcoidosis which were proven by open lung biopsy and developed severe diffuse pulmonary granulomatosis in a few weeks with an associated interstitial fibrosis. In these patients there were diffuse crepitant rales, a dramatic reduction in lung function of 30-60% of lung volumes and diffusion capacity accompanied by major hypoxemia (m +/- DS: 63.3 +/- 4.0 mmHg) without hypercapnia. Bronchoalveolar lavage showed an alveolar neutrophil leucocytosis (7.3 +/- 5.5%) without a lymphocytosis (4.3 +/- 11.5%). In the three cases under study, the clinical picture, the radiological and lung function studies, as well as the data from the bronchoalveolar lavage, were more suggestive of an acute diffuse interstitial fibrosis than of sarcoidosis.
