We report a complex case of early acquired disseminated syphilis causing an ulceronodular rash (lues maligna), orchitis, osteitis and lung nodules in an immunocompetent man who has sex with men who presented to the genitourinary medicine clinic. Syphilis should be considered in the differential diagnoses of multiple clinical presentations and optimal management should involve multidisciplinary care.
