Warts are contagious epidermal growths caused by the Human Papillomavirus (HPV) that settle in the upper layer of the skin, and they can occasionally cause cosmetic or physical discomfort. They can appear on different parts of the body, and there are many clinical options for managing them. In this guide, you can examine in detail the mechanism of wart formation, the routes of transmission, the medical evaluation process, and the current clinical approaches used in dermatology.
1. Causes of Wart (Verruca) Formation and Routes of Transmission
Warts occur when the Human Papillomavirus (HPV) enters the epidermis, the outermost layer of the skin, and triggers excessive proliferation of the cells there. The virus can easily penetrate the tissue through small microscopic scratches, cracks, abrasions, or cuts where the skin’s integrity has been broken.
An individual’s immune response is highly determinative in the emergence and spread of warts. While warts may not develop in every person who comes into contact with the virus, lesions may tend to spread more quickly in people whose immune resistance is temporarily lowered.
Transmission Channels of Warts:
- Direct Contact: Direct touching of an infected wart or skin carrying the virus.
- Indirect Contact (Shared Item Use): Shared use of personal hygiene items such as towels, slippers, nail clippers, files, shoes, or gym equipment.
- Shared Damp Areas: Swimming pools, saunas, jacuzzis, communal showers, and changing rooms are risky environments in terms of preserving the virus’s viability, as they are damp surfaces.
- Autoinoculation (Self-Transmission): The virus being carried to other healthy parts of the body as a result of a person scratching, picking, shaving, or biting their nails near an existing wart on their body.
2. Types of Warts According to Their Location on the Body
Warts are given different names depending on the anatomical region where they settle, the HPV subtype, and their clinical appearance. Correctly identifying the type of wart is important for differential diagnosis and determining the clinical approach:
- Common Warts (Verruca Vulgaris): Lesions usually seen on the hands, fingers, and around the nails, with a rough, hard, and bumpy surface.
- Plantar Warts (Verruca Plantaris): Warts that grow inward on the sole of the foot under the pressure of body weight. They are often confused with deep calluses and can cause a stinging sensation or pain when pressed. Small black clotted capillary points can be found on their surface.
- Flat Warts (Verruca Plana): A type of wart usually seen on the face, neck, back of the hands, and legs; smooth, slightly raised, small, and tending to cluster in large numbers.
- Filiform Warts: Lesions that often settle on the eyelids, lips, face, and neck, growing outward from the skin’s surface as thin, long projections.
- Genital Warts (Condyloma / Condyloma Accuminata): Wart structures that appear in the genital and anal region, forming either singly or in cauliflower-like clusters, with a high likelihood of transmission through sexual contact.
3. What Are the Wart Treatment Options in Dermatology?
The main goal in wart management is to remove the hyperkeratotic tissue caused by the HPV infection and to help the skin regain its natural structure. The method to be applied is determined by a specialist dermatologist based on where the wart is located, the depth and extent of the lesion, and the patient’s general state of health.
A. Topical Medical Applications
These are first-step approaches frequently used for mild and superficial warts. Keratolytic (tissue-dissolving) solutions and ointments containing salicylic acid, lactic acid, or acetic acid are used. These agents aim to shrink the lesion by gradually peeling away the thickened layer of skin. They should only be used with a physician’s recommendation and follow-up.
B. Cryotherapy (Ice/Freezing Treatment)
Cryotherapy is the process of applying very low temperature liquid nitrogen (-196 °C) directly to the wart tissue using a special spray or electrode. The aim is to separate the wart tissue from the healthy layer of skin by creating cellular freezing and necrosis due to extreme cold in the tissue. Mild blistering or crusting may be seen in the area after the application.
C. Electrocauterization (Burning Treatment)
In this method, applied under local anesthesia, the wart tissue is burned and destroyed using an electrocautery device that uses high-frequency electric current, and then cleaned with a curette. It is one of the clinical methods preferred especially for thick, prominent, and resistant lesions.
D. Laser Applications
Laser systems (such as Nd:YAG or Carbon Dioxide CO2 lasers) work by targeting the network of micro capillary vessels that feed the wart tissue, or by vaporizing the tissue. They can be considered especially for warts in difficult areas such as the sole of the foot or around the nails that are resistant to other classic methods.
E. Immunotherapy and Injection Methods
In cases of numerous, widespread, or resistant warts, topical immunomodulatory creams or intralesional injection applications aimed at locally stimulating the body’s immune system may be considered at the physician’s discretion.
4. Comparative Features of Wart Treatment Methods
The key features of the main methods used in clinical applications are summarized in the table below:
| Method | Method of Application | Key Feature | Area of Application |
|---|---|---|---|
| Topical Agents | Applying an acid-containing solution/cream | Can be followed up at home, provides gradual peeling | Superficial and small-sized warts |
| Cryotherapy | Freezing with liquid nitrogen | Practical clinical application, requires no stitches | Warts on the hands, feet, body, and genital area |
| Electrocauterization | Burning tissue with electric current | Potential to achieve tissue destruction in a single session | Raised, hard, and deeply located lesions |
| Laser Applications | Intravascular coagulation/vaporization with light energy | Ability to target with precision | Resistant, thick, and widespread wart foci |
5. Precautions That Can Be Taken to Prevent Warts from Recurring
Even when wart tissue is clinically cleared, there is a risk of warts recurring because the HPV virus can remain dormant in the skin for a period of time. The following hygiene rules should be observed to minimize the risk of recurrence:
- Never pick, cut, or scratch existing wart lesions.
- Do not share your personal items such as shoes, towels, socks, nail clippers, and files with anyone.
- Always use personal slippers in pools, saunas, Turkish baths, and public shower areas.
- Take care to keep your feet dry at all times and prefer cotton socks that prevent sweating.
- Moisturize and protect small cuts and cracks on your hands or skin with a bandage to prevent viral entry.
- Keep your immune system strong with a balanced diet, adequate sleep, and regular lifestyle habits.
6. Özel Demiderm Clinic Medical Evaluation Protocol
Özel Demiderm Clinic carries out the evaluation of skin lesions and warts under the supervision of specialist dermatology physicians. During the diagnostic stage, the structure of the lesion is examined in detail using dermatoscopy devices, clarifying the differential diagnosis from calluses, moles, or other dermatological conditions.
Following the examination, individualized clinical follow-up and medical treatment options are planned taking into account the type and depth of the lesion and the patient’s clinical picture. In accordance with legal regulations, the decision and execution of every medical procedure must be carried out by an authorized physician.
