[A rare complication of antineoplastic BCG therapy: pulmonary tuberculosis]

Local treatment with intra vesical BCG for bladder carcinoma have few complications. Pulmonary side effects are rare, like interstitial pneumonitis. We report a case of a 77-year-old man, treated with BCG for bladder carcinoma who developed illness and tumoral chest-X-ray opacity. Mycobacterium tuberculosis bovis was isolated in culture and 2 years after in sputum. Physio pathologic mechanism of pulmonary features remains controversial, however this case suggest that lung lesions can be result of an infection process.
