[Endobronchial tuberculosis. Report of 21 cases]

Since the advent of antituberculosis drugs, endobronchial tuberculosis has become an exceptional finding, often in a misleading context. Cases reported generally occur in patients with immune deficit. We report 21 cases of endobronchial tuberculosis in immunocompetent patients (mean age 37 years). Clinical and radiological signs were not specific. Bronchial fibroscopy was essential for certain diagnosis, particularly in budding forms. Early treatment reduced the risk of complications. Based on our experience with these 21 cases, we propose a discussion of the pathogenic mechanisms involved and the diagnostic difficulties encountered as well as the disease course and risk of complications that can be expected.
