After an incubation period of between 10 and 90 days (mean: 21 days), a chancre appears at the <span class="elsevierStyleItalic">T. pallidum</span> inoculation site, usually the genital and anal region. The chancre usually consists of a single, painless ulcer with a firm base and hard borders. It is usually accompanied by locoregional lymphadenopathy. This classic clinical presentation of primary syphilis can have less common variations, such as the presence of multiple chancres.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,2</span></a> There is variability in terms of the frequency with which multiple chancres occur in the different series, with some reports as high as 47%, as well as some debate as to whether or not this is more common in HIV-positive patients.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a></p><p id="par0030" class="elsevierStylePara elsevierViewall">Serology is the main investigation for confirming the diagnosis of syphilis. One of its drawbacks is that it can be negative in the initial stages of the infection. After the appearance of the chancre, the treponemal tests take 5–15 days to become positive and the non-treponemal tests take 10–15 days. In these cases, we can opt to repeat the test after the window period or perform direct identification techniques for <span class="elsevierStyleItalic">T. pallidum</span> in the syphilitic chancre.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> Classically, the technique used for this purpose was dark-field microscopy.

Drawbacks include a higher cost and the lack of immediacy, although the result usually only takes a few days.
