Prominent osseous and unusual dermatologic manifestations of early syphilis in two patients with discordant serological statuses for human immunodeficiency virus infection.

Numerous case reports of atypical and/or severe forms of syphilis in individuals coinfected with human immunodeficiency virus (HIV) have led many authorities to conclude that HIV exacerbates early syphilitic infection. Herein we report prominent osseous and unusual dermatologic manifestations of early syphilis in two individuals whose serostatuses for HIV infection were discordant. Our cases emphasize the need for caution before conclusions are drawn from anecdotal data about the interactions between HIV infection and syphilis.
