Penile tuberculosis after intravesical bacille Calmette-Guérin immunotherapy.

Immunotherapy with bacille Calmette-Guérin (BCG) is widely used for treatment of superficial urothelial cancer. Complications associated with BCG treatment are common. The most common are minor reactions as cystitis, hematuria, fever, malaise. We report an unusual case of granulomatous balanoposthitis as a complication of intravesical BCG instillation therapy. To our knowledge, only a few reports of BCG-related penile or urethral granulomatous infection have been previously published in the literature.
