[Bird fancier's lung and Crohn disease. Apropos of a case].

Abstract

The case of pigeon breeders' disease reported here is peculiar not only because of the large number of birds with which the patient was in contact, but also because the disease developed in a patient presenting with both pulmonary tuberculosis and Crohn's disease. Moreover, 18 months after eviction of the birds and beginning of corticosteroid therapy, the number of lymphocytes in fluid from broncho-alveolar lavage remained high.
