The syphilis is more dangerous than the warts, the syphilis lesions can involve almost all organs of the body, syphilis can cause skin damage, but also cardiovascular syphilis, bone syphilis, neurosyphilis, etc. The lesions of condyloma acuminata mainly involve the external genitalia and the anus. If warts are left untreated, they may fade on their own or remain unchanged, along with increased and enlarged superfluities. If syphilis is not treated, it will not heal on its own and will gradually worsen and affect other organs. Syphilis can be life-threatening if it gets worse, while warts are not life-threatening.
