In the early stages of syphilis in women, a hard chancre appears, often accompanied by swollen inguinal lymph nodes. These nodes are about the size of a finger, relatively hard, non-fusing, painless, and without tenderness; their surfaces exhibit no redness, swelling, or signs of inflammation such as fever. The lymph fluid from a puncture will contain Treponema pallidum (the syphilis bacterium). During the early stage of syphilis, the appearance of a hard chancre significantly increases the positivity rate for syphilis. If the hard chancre is not treated timely, it generally disappears naturally within three to four weeks, after which it enters the latent phase of secondary syphilis. The second stage of syphilis is typically characterized by patches of varying-sized erythemas on the trunk and copper-red, symmetrical maculopapular rashes on the palms and soles. Upon detection of syphilis, prompt and thorough treatment is essential.
