Verruca plana, also known as flat warts, is a type of wart caused by the human papillomavirus (HPV). They are benign skin growths and are usually small, smooth, and flat-topped, appearing slightly raised from the skin. Verruca plana is more common in children and young adults and tends to occur on areas such as the face, neck, back of the hands, and legs.
Causes of Verruca Plana
1. Human Papillomavirus (HPV):
• Specifically caused by low-risk HPV types, such as HPV-3, HPV-10, HPV-28, and HPV-49.
• The virus enters through small breaks or abrasions in the skin.
2. Spread:
• Direct skin-to-skin contact.
• Indirect contact with contaminated objects, such as towels or razors.
• Autoinoculation, where scratching or shaving spreads the warts to other parts of the body.
3. Risk Factors:
• Weakened immune system: More common in individuals with compromised immunity.
• Skin trauma: Cuts, abrasions, or frequent shaving increase susceptibility.
• Age: Predominantly seen in children and young adults.
• Close contact: Living with or sharing personal items with someone who has warts.
Symptoms of Verruca Plana:
• Small, flat, smooth, and flesh-colored or slightly brownish lesions.
• Often clustered in groups.
• Painless, but may cause mild irritation or itching.
Prevention:
• Avoid direct contact with warts on others.
• Practice good hygiene.
• Avoid sharing personal items like towels or razors.
• Treat cuts or abrasions promptly to reduce the risk of HPV entry.
Treatment Options:
• Topical treatments: Salicylic acid, retinoids, or imiquimod.
• Cryotherapy: Freezing the warts with liquid nitrogen.
• Laser therapy: For resistant cases.
• Immune-modulating therapies: To boost the body’s immune response to the virus.
• Many cases resolve spontaneously as the immune system clears the virus.
If persistent or widespread, consulting a dermatologist is recommended for effective management.
