Abstract

BCG (Bacillus Calmette-Guérin) immunotherapy is a method which is an emerging form of cancer treatment. BCG attaches to the bladder wall and stimulates an immune response to destroy the cancer cells. Complications of BCG therapy are due to reactivated infection or a hypersensitivity reaction and thus may be treated with antimycobacterial agents, corticosteroids, or both. BCG therapy instillations should also be stopped if complications occur during the treatment period. We present a case wherein a subject sufferef from a disseminated BCG infection 2 years after BCG instillation.
