A case of giant condyloma latum in vulvar and perianal areas

Condyloma latum is a typical lesion of secondary syphilis，which usually appears in the vicinity of the initial chancre. It is found that treponema pallidum load in condyloma latum is significantly higher than that in other secondary syphilis. We report a case of mesosyphilis presented as giant flat condyloma latum in vulvar and perianal areas. A 17-year female patient came to our clinic，complaining of plaques in vulvar and perianal areas more than 2 months. Physical examination showed giant red moist plaques in vulvar and perianal areas. The titer of non-specific antibody for syphilis was 1∶64 and the specific antibody test for syphilis showed a value of 189.000 COI. The patient was diagnosed as secondary syphilis and treate with benzathine penicillin. The rash subsided after 3-week treatment. This case of condyloma latum with giant red plaques was easily misdiagnosed as condyloma acuminatum.
