Stevens Johnson Syndrome versus Jarisch Herxheimer Reaction in an HIV Positive Patient with Secondary Syphilis.

Background: HIV positive patients can suffer many complications due to infectious diseases. A sever drug reaction to some of the drugs involved in the treatment can overlap the symptoms of the infections, making the diagnosis very difficult. We present the case of a 28-year-old-man, HIV positive, with secondary syphilis, who developed a Stevens Johnson Syndrome (SJS) caused by one of the many drugs he received.
