Effect of corticosteroids on deterioration of endobronchial tuberculosis during chemotherapy

A 26-year-old man had endobronchial tuberculosis diagnosed on bronchoscopy. He was treated with standard antituberculosis drugs, but the endobronchial lesions deteriorated bronchoscopically. This is believed to be a hypersensitivity reaction to tuberculoprotein. The lesions improved rapidly with addition of corticosteroids.
