Primary Syphilis

Primary syphilis is the first stage of a sexually transmitted infection caused by a bacterium. It is distinguished by the appearance of an initial lesion, usually painless, at the site where the microorganism entered.

How it presents: a single, firm, painless ulcer, which can go unnoticed and disappear on its own even though the infection continues.

Why it is important to treat: since it causes little discomfort, it is often underestimated, but it requires timely identification to prevent it from progressing to later stages.

Which specialist treats it? A dermatologist can evaluate it or, in the context of sexual and reproductive health, a gynecologist. In the face of any genital lesion or suspicion of infection, the most responsible thing is to seek a professional evaluation promptly.
