Viral wart removal is a procedure that eliminates abnormal skin growths caused by human papillomavirus (HPV) infection. The procedure targets the virus-infected tissue through various methods, including cryotherapy, topical treatment, electrosurgery, or surgical excision. Wart removal aims to eradicate the infected tissue, prevent spread to other body areas or individuals, and restore normal skin appearance and function while minimising scarring.

Indications for Viral Wart Removal

Patients may consider wart removal treatment by a dermatologist when experiencing specific symptoms or conditions that affect comfort or appearance, or when the warts persist despite home treatments.

Persistent Warts: Warts that have remained present for more than 6-12 months may require professional removal. The immune system sometimes fails to recognise and clear the virus on its own.
Pain or Discomfort: Warts in pressure-bearing areas such as the soles of feet (plantar warts) or palms can cause pain during walking or hand use. These pressure points make the warts grow inward, creating deeper tissue disruption.
Multiple or Spreading Warts: Clusters of warts or new growths appearing in different body areas indicate active viral replication. These patterns suggest the virus is spreading and may continue to produce additional warts if not addressed.
Cosmetic Concerns: Visible warts, particularly on the face, neck, or hands, can affect appearance. Facial warts often prompt treatment due to their visibility during social interactions.
Risk of Transmission: Genital warts require treatment due to their contagious nature. These warts spread through direct contact and certain HPV strains have associations with increased cancer risks.

Benefits of Viral Wart Removal

Wart removal procedures offer several advantages for patients dealing with HPV-induced skin lesions compared to leaving them untreated or attempting home remedies.

Symptom Relief

Removal of warts can alleviate pain, itching, or bleeding associated with the lesions. Plantar warts on the feet often cause discomfort during walking that resolves after treatment.
Prevention of Spread

Treating warts reduces the risk of autoinoculation (spreading to other body areas) and transmission to other individuals. HPV remains contagious while the wart is present on the skin.
Cosmetic Improvement

Removal restores normal skin texture and appearance. Warts typically create rough texture, colour variations, and raised surfaces that return to normal after successful treatment.
Quicker Resolution

Professional treatment typically resolves warts faster than waiting for spontaneous immune clearance. Untreated warts may persist for months to years, while medical intervention often produces results within weeks or months. Treatment success depends on individual immune response.
Lower Recurrence Rates

Complete removal of the infected tissue may reduce the likelihood of warts returning in the same location. Some treatment methods also trigger immune responses that help the body recognise and fight HPV. Recurrence rates depend on individual immune response.

Treatment Methods

Topical Treatment

This treatment is usually painless, however, it may require multiple sessions and regular application to resolve the warts. There are a few methods: topical salycylic acid, fluorouracil, imiquimoid and cantharidine +/- podophyllin. These treatments can be applied at home, except for catharidine +/- podophyllin, which must be applied by a doctor.

Cryotherapy

This method uses liquid nitrogen to freeze the wart tissue at temperatures between -196°C and -210°C. The freezing creates ice crystals within cells, causing cellular destruction and tissue death. The treated area forms a blister, which eventually falls off, taking the wart tissue with it.

Electrosurgery and Curettage

This combined approach involves scraping away the wart tissue with a curette (a spoon-shaped instrument) followed by electrocautery to destroy remaining abnormal tissue and control bleeding. The procedure removes the visible portion of the wart along with a margin of surrounding tissue to reduce recurrence risk.

Laser Therapy

Laser treatment uses focused light energy to selectively destroy wart blood vessels, causing the tissue to die and eventually fall off. It allows for targeted treatment with minimal damage to surrounding healthy skin. CO2 lasers vaporise the wart tissue layer by layer, while pulsed dye lasers target the blood vessels supplying the wart. Laser therapy works well for resistant warts or those in sensitive areas.

Surgical Excision

This method involves cutting out the wart with a scalpel under local anaesthesia. The procedure removes the entire wart in one session, and the specimen can be sent for pathological examination if needed. Excision works best for isolated, large, or suspicious lesions.

Preparing for the Procedure

Diagnostic Assessment: Clinical examination confirms the diagnosis and determines the appropriate treatment method. This assessment evaluates the wart type, location, size, and number, along with any previous treatments attempted. A dermatoscope (magnifying device) helps distinguish warts from similar-appearing conditions such as corns, calluses, or other skin lesions.

Medication Adjustments: Some medications may need temporary adjustment before certain wart removal procedures. Blood thinners may need to be discontinued before surgical excision to reduce bleeding risk.

Pre-procedure Skin Preparation: For some treatments, pre-softening the wart may enhance effectiveness. Pre-treatment instructions may include applying salicylic acid preparations or soaking the area before the appointment. Keeping the area clean and avoiding application of creams, lotions, or oils on the treatment day ensures optimal contact with the wart tissue.

Step-by-Step Procedure

Preparation

The treatment area is cleaned with antiseptic solution to reduce infection risk. Standard precautions, including gloves and appropriate personal protective equipment, are used. For procedures requiring sterility, the area may be draped to create a sterile field.

Anaesthesia Administration

Local anaesthesia may be applied or injected depending on the procedure type and location. Cryotherapy often proceeds without anaesthesia for small warts, while surgical excision requires injectable lidocaine or similar anaesthetics. The anaesthetic takes effect within minutes, numbing the area completely before the procedure begins.

Wart Removal Technique Application

The selected treatment method is applied according to established protocols. For cryotherapy, liquid nitrogen is applied precisely to the wart using a spray device or cotton swab for 5-20 seconds, depending on the wart characteristics. With electrosurgery, the curette removes bulk wart tissue before cautery seals the base. Laser therapy delivers calibrated energy pulses to the targeted tissue.

Wound Management

After removal, the treatment site is assessed for bleeding or other immediate concerns. The wound may be left open to heal or closed with sutures, depending on the procedure type and location.

Post-Procedure Care and Recovery

Immediate Care

For the first 6-24 hours, a bandage or dressing may be necessary to absorb any drainage or protect the site from contamination. Pain or discomfort typically responds well to over-the-counter pain relievers such as paracetamol.
Activity Adjustments

Reduce activities that could irritate the treated area until healing is complete. For foot warts, you may need to limit walking for several days, and special padding can help redistribute pressure away from the treatment site. Avoid swimming pools and public showers until the site has fully healed to prevent infection and potential spread of remaining viral particles.
Monitoring Healing Progress

Normal healing includes initial redness, mild swelling, and possibly blister formation depending on the treatment method. A scab typically forms and falls off naturally within 1-3 weeks. New skin appearing underneath should gradually blend with the surrounding tissue. Healing time varies based on treatment method, wart location, and individual factors such as age and overall health status.
Follow-up Care

Attend all scheduled follow-up appointments to assess healing and treatment effectiveness. Some wart removal methods require a series of treatments spaced several weeks apart for complete resolution.

Potential Risks and Complications

Wart removal procedures may cause temporary discomfort, redness, swelling, or blistering during healing. Infection is possible if the wound is not kept clean. Some cases develop temporary hyperpigmentation or hypopigmentation at the treatment site. Persistent pain indicates a need for reassessment. Nerve damage occurs rarely with deeper treatments, potentially causing numbness or tingling. Individuals with darker skin tones have higher risks of pigmentation changes, while those with compromised immune systems may experience delayed healing or more frequent recurrences.

Frequently Asked Questions

Can warts go away without treatment?

Approximately two-thirds of warts will eventually clear spontaneously within 2 years due to the body’s immune response. However, this timeline is unpredictable, and during this period, warts can spread or cause discomfort.

Does treating warts early reduce recurrence risk?

Early treatment generally reduces recurrence risk. Smaller, newer warts have not established deep roots in the skin and contain less viral load, making complete removal more likely. Additionally, warts present for less than six months tend to respond better to treatment, suggesting that the virus has not fully established persistent infection in surrounding tissues.

Will wart removal cause scarring?

The potential for scarring depends on the removal method, wart location, size, and your skin type. Cryotherapy typically has minimal scarring risk, while surgical excision carries a higher risk of visible scarring. Most minor scars fade over 6-12 months, and following proper wound care instructions significantly reduces scarring potential.
