Flat warts


Hello doctor, I would like to ask about flat warts.
After electrosurgery, although the scab has fallen off, the area is still red and feels bumpy to the touch.
Does this mean the treatment was not effective? Should I apply any medication, or will it resolve on its own?

I cannot identify the lesion, so I cannot determine the issue.
You should consult your attending physician, as they are most familiar with your condition.

More Info


Flat warts, also known as verrucae planae, are benign growths caused by the human papillomavirus (HPV). They typically appear as small, smooth, flat-topped bumps on the skin and can occur anywhere on the body, but are most commonly found on the face, neck, hands, and legs. Treatment options for flat warts include topical therapies, cryotherapy, laser treatment, and electrosurgery, among others.
From your description, it seems you have undergone electrosurgery to remove the flat warts, which is a common and effective method. After the procedure, it is normal for the treated area to form a scab as part of the healing process. The redness and raised texture you are experiencing may indicate that the area is still healing. It is essential to understand that complete healing can take time, and the appearance of the skin may change as it heals.

Here are some key points to consider regarding your situation:
1. Healing Process: After electrosurgery, the skin will go through several stages of healing. Initially, you may notice redness and swelling, followed by the formation of a scab. Once the scab falls off, the underlying skin may still appear pink or discolored, and it might feel slightly raised or textured. This is part of the normal healing process, and it can take several weeks to months for the skin to return to its normal appearance.

2. Topical Treatments: While the area is healing, it is crucial to keep it clean and moisturized. You may apply a gentle, fragrance-free moisturizer to help with the healing process. If your doctor has recommended any specific topical treatments, such as silicone gel or ointments, be sure to follow their instructions. Avoid using harsh chemicals or irritants on the area until it has fully healed.

3. Monitoring for Infection: Keep an eye on the treated area for signs of infection, such as increased redness, swelling, warmth, or discharge. If you notice any of these symptoms, it is essential to contact your healthcare provider for further evaluation.

4. Follow-Up Care: It is advisable to have a follow-up appointment with your dermatologist or healthcare provider to assess the healing process. They can determine if additional treatments are necessary or if the area is healing as expected.

5. Self-Resolution: In some cases, flat warts may resolve on their own over time, especially in younger individuals with a robust immune response. However, if the warts persist or if you have concerns about their appearance, further treatment options are available.

6. Avoid Picking or Scratching: It is crucial to avoid picking at the scab or the surrounding skin, as this can lead to scarring or infection. Allow the area to heal naturally.

In summary, the redness and raised texture you are experiencing after electrosurgery for flat warts are likely part of the normal healing process. It is essential to care for the area properly and monitor for any signs of complications. If you have concerns about the healing process or if the area does not improve over time, do not hesitate to reach out to your healthcare provider for further guidance. They can provide you with the best advice tailored to your specific situation and ensure that you achieve the best possible outcome.
