Extrinsic allergic alveolitis with an atypical immune expression.
Extrinsic allergic alveolitis and sarcoidosis are two granulomatosis of the lung characterized by non- -necrotizing granuloma. Both have typical bronchoalveolar lavage immunology, with opposite CD4/CD8 relation. However, sarcoidosis does not have such well defined etiology as extrinsic allergic alveolitis. The authors present two cases with similar clinical course, imagiology, lung function and immunology, although they both had an histology that was not concordant with the bronchoalveolar lavage, and with the peculiarity of being two elements of the same family, co -inhabitants and with a clinical presentation only a few weeks apart.
