Genital Sores with White Spots: Key STI Indicators Requiring Prompt Medical Evaluation

Do not attempt to self-diagnose or self-treat. A sore, itchy genital lesion accompanied by white spots can signal several distinct infectious or inflammatory conditions, each requiring specific management.

Common Causes

• Herpes Simplex Virus (HSV-1/2): Presents as grouped vesicles that rupture into painful ulcers; recurrences are typical.
• Syphilis (Primary Stage): A single, usually painless chancre with a clean base and serosanguinous exudate.
• Candidiasis (Yeast Infection): Characterized by adherent white plaques, intense pruritus, and satellite lesions.
• Human Papillomavirus (Genital Warts): Flesh-colored or white papules, often asymptomatic but sometimes itchy.
• Lichen Sclerosus: White, atrophic, "cigarette-paper" plaques with severe itching; non-infectious but chronic.

Essential Steps for Evaluation

1. See a clinician—dermatology, gynecology, urology, or a sexual health clinic.
2. Expect a thorough exam plus targeted testing: NAAT swabs for HSV, syphilis, gonorrhea, chlamydia; KOH preparation for yeast; and serology (RPR, HIV).
3. Abstain from sexual activity until diagnosis is confirmed and treatment initiated.
4. Notify partners if an STI is diagnosed, to facilitate their testing and treatment.

Delaying care risks complications such as pelvic inflammatory disease, infertility, systemic spread of infection, and ongoing transmission to others. Early intervention is crucial.
