Bacille Calmette-Guerin disease following Bacille Calmette-Guerin vaccination of an HIV-infected health-care worker.

We present a case of Bacille Calmette-Guerin (BCG) lymphadenitis following immunization of a health-care worker with risk factors for HIV but undiagnosed infection. This case highlights the potential risks of BCG and clearly demonstrates the need to consider HIV testing in all patients prior to BCG vaccination.
