Introduction
Primary, secondary, and tertiary syphilis are typically diagnosed based on clinical symptoms:
1. Primary syphilis: Lesions usually appear on the genitalia.
2. Secondary syphilis: Generally occurs 2–3 months after infection and may cause roseola or psoriasis-like rashes on the limbs and body.
3. Tertiary syphilis: Often leads to abnormalities in the bones and cardiovascular system, potentially causing localized pain.
Primary, secondary, and tertiary syphilis are typically diagnosed based on clinical symptoms.
1. Primary syphilis: Lesions usually appear on the genitalia, presenting as localized, indurated, reddish plaques. Dark-red, raised lesions may also develop, accompanied by noticeable local pruritus and swelling. Treatment generally involves antibiotics prescribed by a physician—commonly penicillin, tetracycline hydrochloride, or erythromycin.
2. Secondary syphilis: Typically occurring 2–3 months after infection, it may manifest as pityriasis rosea- or psoriasis-like rashes on the limbs, localized lymphadenopathy, or dark-red infiltrative lesions around the anus. Treatment options include minocycline or penicillin, administered per medical prescription.
3. Tertiary syphilis: This stage often affects the skeletal and cardiovascular systems, causing localized pain, arthralgia, and, in severe cases, impaired mobility. Intravenous penicillin is the standard treatment, as prescribed by a physician; alternatively, oral ceftriaxone may be used.
During treatment and recovery, strict attention to personal hygiene is essential—avoid wearing contaminated undergarments.
