Can Flat Warts Heal on Their Own? Symptoms and Treatment - Dermatology

More Info

---

Flat warts, also known as verrucae planae, are benign growths caused by the human papillomavirus (HPV). They commonly appear on the face, hands, and legs and are characterized by their smooth, flat surface. Your experience with flat warts and the subsequent symptoms you are experiencing raises several important points regarding their natural course, immune response, and treatment options.


Question 1: Is the itching and redness a sign that the flat warts are about to heal on their own?
The symptoms you describe—itching, redness, and swelling—could indicate that your immune system is responding to the presence of the HPV virus. In some cases, the immune system can recognize and attack the virus, leading to inflammation and the eventual resolution of the warts. This immune response can sometimes cause the warts to become more pronounced before they start to shrink and disappear. However, it is essential to note that while some flat warts may resolve spontaneously, this does not happen for everyone, and the timeline can vary significantly from person to person.


Question 2: Will the warts disappear on their own after the immune system attacks them?
Yes, flat warts can sometimes resolve on their own as the immune system mounts a response against the virus. This process can take weeks to months, and in some cases, it may take years. However, it is not guaranteed that all warts will disappear without treatment. If your immune system is effectively targeting the warts, you may notice a reduction in their size and number over time. However, if the warts persist or worsen, it may be necessary to seek further treatment options.


Question 3: After the warts disappear, will the skin return to normal, or will there be scars?
The appearance of the skin after the warts resolve can vary. In many cases, the skin may return to its normal appearance without any scarring. However, some individuals may experience post-inflammatory hyperpigmentation or slight textural changes, especially if the warts were inflamed or scratched. It is crucial to avoid picking at the warts or the surrounding skin, as this can lead to further irritation and potential scarring.


Treatment Options
Given your history of flat warts and the recent changes in your skin, it may be beneficial to consult a dermatologist for a thorough evaluation. While you have previously undergone cryotherapy and used topical treatments like imiquimod (the medication you referred to as "樂得美"), there are several other treatment options available, including:
1. Cryotherapy: Repeated freezing of the warts can be effective, especially if done multiple times.

2. Topical Treatments: Other topical agents, such as salicylic acid or cantharidin, may be recommended.

3. Laser Therapy: This can be an option for stubborn warts that do not respond to other treatments.

4. Immunotherapy: This approach aims to stimulate the immune system to fight the virus more effectively.


Conclusion
In summary, while flat warts can sometimes heal on their own due to an immune response, it is essential to monitor your symptoms closely. If the warts continue to itch, become painful, or show no signs of improvement, it would be wise to seek further medical advice. A dermatologist can provide tailored treatment options based on your specific situation and help manage any discomfort you may be experiencing. Remember, patience is key, as the immune response can take time to effectively clear the virus and resolve the warts.
