RESUMO
Syphilis, caused by Treponema pallidum subsp. pallidum, remains a global health challenge, with a significant burden of new cases annually. The disease disproportionately affects men who have sex with men (MSMs) and endemic, low-income regions. While secondary syphilis typically manifests with a polymorphic rash, individuals with human immunodeficiency virus (HIV) coinfection may present with varied signs and symptoms. Here, we report a case of a 21-year-old male student with painful target lesions on his genitalia, deviating from the typical syphilis presentation. He was found to have concurrent molluscum contagiosum and HIV-1 infection. Serologic testing confirmed syphilis and anti-HIV-1 antibodies. Prompt initiation of antiretroviral therapy and benzathine penicillin G led to symptom resolution. This case highlights the importance of recognizing atypical painful target lesions as a potential manifestation of syphilis, especially in patients with HIV coinfection, to ensure timely diagnosis and treatment.
