Sexually transmitted diseases in a HIV infected patient.

We report a case of HIV infection with herpes simplex, syphilis, and condyloma acuminatum in a 66-year-old heterosexual man. The patient was an asymptomatic carrier (group II) of HIV infection. Herpes simplex on his penis was controlled by aciclovir. Secondary syphilis was treated with penicillin G, after which skin lesions disappeared. These four diseases were all sexually transmitted diseases (STD). One should consider the possible existence of other STD in similar cases.
