Where is the chancre located?
Recently, I heard that a friend was diagnosed with syphilis and had developed a hard chancre lesion. He told me that this symptom mainly appears in the genital area, but I don't know much about this condition and would like to learn more about the specific locations where chancres can appear, as well as their characteristics and manifestations.

Chancre is a typical early symptom of syphilis, usually appearing at the site where Treponema pallidum enters the body. It commonly occurs in the genital area, including the penis, vagina, around the anus, and even inside the mouth.
A chancre is characterized by a painless ulcer with a well-defined border, flat base, and mild redness around the lesion, with minimal discharge. Chancres are usually solitary, but multiple lesions can also occur. If symptoms resembling a chancre appear, such as ulcers or erosion on the skin, patients should seek medical attention promptly for diagnosis and treatment. Syphilis treatment should follow the principles of early intervention, adequate dosage, and regular medication use to ensure effectiveness and prevent disease progression. Additionally, patients should maintain good personal hygiene and take precautions to avoid transmitting the disease to others.
