Tuberculous Granuloma in the Scrotal Skin After Intravesical Bacillus Calmette-Guerin Therapy for Bladder Cancer: A Case Report

Rare cases of tuberculous urinary tract or genital infection caused by intravesical Intravesical Bacillus Calmette-Guerin (BCG) instillation therapy have been reported. We encountered a patient with tuberculous granuloma in the scrotal skin after intravesical BCG therapy for bladder cancer. There was evidence of infection in the scrotal skin, but not in the epididymis. To the best of our knowledge, this is the first report of tuberculous granuloma in the scrotal skin without epididymitis after intravesical BCG therapy. In our case, lower urinary tract symptoms such as the terminal dribbling of urine appear to support the theory of direct BCG inoculation.
