Endobronchial tuberculosis mimicking lung cancer in elderly patients.

We report four elderly patients with cough who were referred with the presumptive diagnosis of bronchial carcinoma based on chest X-ray and the macroscopic view on fibreoptic bronchoscopy, but whose final diagnosis was endobronchial tuberculosis. Chest X-ray showed atypical pulmonary infiltrates in three patients, but was normal in one. Bronchoscopic examination revealed ulcerative and/or stenotic lesions. Endobronchial tuberculosis should be considered in differential diagnosis, especially in the elderly.
