Abstract:
We report two cases of pulmonary BCG-induced pneumonitis recently diagnosed amongst our patients. The first case is a 81 year old man under BCG bladder instillation treatment because of high grade superficial bladder cancer who developed a severe interstitial granulomatous pneumonitis. The patient was treated with corticosteroids and tuberculostatics with a rapid and complete response. The second patient is a young man who presented only with persistent fever and also had a complete response after treatment.
