Justified Suspicion: Symptomatic Syphilitic Alopecia in a Patient with Well-Controlled HIV.

Background: An estimated 25% of primary and secondary syphilis, a sexually transmitted infection caused by the spirochete bacterium , occurs in patients coinfected with human immunodeficiency virus (HIV) (Chesson et al., 2005). This association is especially evident in men who have sex with men (MSM).
