Secondary syphilis and human immunodeficiency virus coinfection
Since it was first defined, human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome has become one of the most studied infectious diseases. Syphilis is a sexually transmitted chronic infection, which can affect all systems and organs with different clinical stages, and Treponema pallidum, a member of the spirochete family, is the agent. Syphilis has led to numerous epidemics worldwide, which started in the 1990s and still ongoing with the increase of HIV-infected patients. Despite the decline in the United States and Europe, it has increased since 2000. It is noteworthy that syphilis shows high rates of coinfection with HIV and HIV-infection may alter the clinical signs of syphilis. Since these two infections can be frequently seen together, all HIV-infected patients should be tested for syphilis. In this report, a case with HIV coinfection with the secondary syphilitic skin lesions is presented.
