Warts and Plantar Warts: Symptoms, Causes, Treatment
What are the types of warts?
There are several types of warts, which are non-cancerous skin growths caused by the human papillomavirus (HPV). The main types of warts include:
- Common warts (verruca vulgaris): These warts typically appear on the hands, fingers, and around the nails. They are often rough, raised, and have a cauliflower-like appearance.
- Plantar warts: These warts appear on the soles of the feet and can be painful, especially when walking or standing. They are often flat and have a rough, grainy appearance with small black dots (clotted blood vessels) in the center.
- Flat warts (verruca plana): These warts are small, smooth, and flat-topped. They can appear in large numbers, often on the face, neck, hands, wrists, or knees.
- Filiform warts: These warts are long and narrow in shape, resembling a small thread or finger-like projection. They often appear on the face, especially around the eyes, nose, or mouth.
- Periungual warts: These warts appear around or under the nails and can be painful. They can distort the nail and affect its growth.
- Genital warts: Also known as condylomata acuminata, these warts appear on the genital and anal areas. They are typically soft, moist, and flesh-colored, and they can occur singly or in clusters. Genital warts are caused by specific strains of HPV that are transmitted through sexual contact.
- Mosaic warts: These warts occur in clusters on the hands or feet and can be difficult to treat.
The appearance and characteristics of warts can vary depending on the type of wart and the individual. It’s important to consult with a healthcare provider for an accurate diagnosis and appropriate treatment for warts.
What are the causes of warts?
Warts are caused by infection with the human papillomavirus (HPV), which is a group of more than 100 related viruses. HPV infects the top layer of skin, usually entering the body through a cut or abrasion. The virus causes the skin cells to grow rapidly, leading to the formation of a wart.
The specific type of HPV that causes a wart to develop can determine the appearance and location of the wart. For example, common warts are usually caused by HPV types 2 and 4, while plantar warts are often caused by HPV types 1, 2, 4, or 63. Genital warts are caused by specific strains of HPV that are transmitted through sexual contact.
HPV is a contagious virus, and warts can be spread from person to person through direct contact with a wart or with an object that has been in contact with a wart. Warts are more likely to develop in areas of the skin that are moist, warm, or damaged, as the virus thrives in these conditions.
Certain factors can increase the risk of developing warts, including:
- Weakened immune system: People with weakened immune systems, such as those with HIV/AIDS or those taking immunosuppressive medications, are more susceptible to HPV infection and may be more likely to develop warts.
- Skin-to-skin contact: Coming into contact with someone who has warts or with surfaces that have been in contact with warts can increase the risk of developing warts.
- Age: Warts are more common in children and young adults, as their immune systems are still developing and they may be more likely to come into contact with the virus.
- Walking barefoot in public places: People who walk barefoot in public places, such as swimming pools, locker rooms, or communal showers, may be at higher risk of developing plantar warts.
- Nail biting or picking at hangnails: These behaviors can create openings in the skin that allow the virus to enter and cause a wart to develop.
It’s important to note that not everyone who is exposed to HPV will develop warts, and some people may be more susceptible to the virus than others. If you have concerns about warts or are experiencing symptoms, it’s important to see a healthcare provider for an evaluation and appropriate treatment.
What is the treatment for warts?
Treatment for warts depends on the type of wart, its location, and the individual’s preferences. While many warts will eventually resolve on their own without treatment, some people may choose to seek treatment to speed up the process or to reduce symptoms. Common treatments for warts include:
- Over-the-counter (OTC) treatments: There are several OTC treatments available for warts, including salicylic acid-based products (such as Compound W) and cryotherapy products (such as Dr. Scholl’s Freeze Away). These treatments are applied directly to the wart and work by breaking down the skin cells infected with the virus.
- Prescription treatments: In some cases, a healthcare provider may prescribe stronger medications, such as topical retinoids or immune system modulators, to treat warts.
- Cryotherapy: This treatment involves freezing the wart with liquid nitrogen, which causes the wart to blister and eventually fall off. Cryotherapy is usually performed in a healthcare provider’s office.
- Electrosurgery: In this procedure, a healthcare provider uses an electric current to burn off the wart. Electrosurgery is usually performed in a healthcare provider’s office and may require local anesthesia.
- Laser treatment: Laser therapy uses a focused beam of light to destroy the wart tissue. Laser treatment is usually performed in a healthcare provider’s office and may require local anesthesia.
- Surgical removal: In some cases, a healthcare provider may recommend surgical removal of the wart. This may be done using a scalpel or a curette (a spoon-shaped instrument) to remove the wart tissue.
- Immunotherapy: This treatment involves injecting a medication into the wart to stimulate the immune system to attack the virus. Immunotherapy is typically used for warts that have not responded to other treatments.
- Intralesional bleomycin: This treatment involves injecting a medication called bleomycin directly into the wart. Bleomycin is a chemotherapy drug that can help shrink the wart.
It’s important to note that no single treatment works for everyone, and multiple treatments may be needed to completely eliminate a wart. Additionally, warts can sometimes recur after treatment, especially if the virus is still present in the body. If you have concerns about warts or are experiencing symptoms, it’s important to see a healthcare provider for an evaluation and appropriate treatment.
