HPV Symptoms and Signs: What to Look For

Human papillomavirus (HPV) infection manifests differently depending on the genotype (low-risk vs. high-risk) and site of infection.

Cutaneous and Mucosal Warts (Low-Risk HPV: 6, 11, 1, 2, 4, etc.)

• Genital warts (condylomata acuminata): Soft, flesh-colored, cauliflower-like or flat papules on genitalia, perineum, perianal area, vagina, cervix. Often asymptomatic; may itch, bleed, or obstruct.
• Common warts (verruca vulgaris): Hands, fingers, knees.
• Plantar warts: Soles of feet; painful, endophytic.
• Flat warts: Face, legs, beard area; smooth, flat-topped.

High-Risk HPV (16, 18, 31, 33, 45, etc.) — Precancer and Cancer

• Cervical: CIN (dysplasia) → cervical cancer. Screening: Pap + HPV co-testing.
• Anogenital: Anal, vulvar, vaginal, penile cancer precursors.
• Oropharyngeal: Tonsil/base of tongue cancer (rising incidence in men).

Early high-risk HPV infection is usually asymptomatic. Cancer symptoms appear late: abnormal bleeding, pain, mass, weight loss.

Diagnosis

• Pap test (cytology): Detects cellular abnormalities.
• HPV DNA/RNA testing: Identifies high-risk genotypes.
• Colposcopy + biopsy: For abnormal screening.
• Anoscopy: For anal dysplasia (high-risk groups).

Management

• Warts: Topicals (imiquimod, podophyllotoxin, sinecatechins), ablative (cryo, laser, excision), immune modulators. Recurrence common.
• Precancer (CIN, VIN, VaIN, AIN): Excision (LEEP, laser), ablation, topical (5-FU, imiquimod).
• Cancer: Surgery, radiation, chemotherapy per stage/site.
• Prevention: 9-valent HPV vaccine (Gardasil 9) — covers 7 high-risk + 2 low-risk types. Recommended ages 9–26; shared decision-making 27–45.

Most HPV infections clear spontaneously. Persistent high-risk infection drives carcinogenesis. Vaccination and screening are the cornerstones of prevention.
