Understanding the distinctions between common skin conditions is essential for accurate identification and appropriate treatment. Two such conditions often mistaken for one another are corns and warts. While both can appear as small growths on the skin, they are fundamentally different in their causes, characteristics, and treatments. By examining the unique features of corns and warts, individuals can better differentiate between these two ailments and make informed decisions about their management and care.

Corn vs Wart: Quick Overview
A corn is a type of thickened skin that typically forms on the feet due to friction or pressure, while a wart is a small, rough growth caused by a viral infection. Corns are non-infectious and result from constant pressure, while warts are contagious and caused by the human papillomavirus (HPV).
Here’s a table highlighting the key differences between a “corn” and a “wart”:
| Characteristic | Corn | Wart |
|---|---|---|
| Cause | Pressure/friction on the skin, often from ill-fitting shoes or repetitive actions. | Viral infection caused by the human papillomavirus (HPV). |
| Appearance | Thickened, hardened skin with a central core that can be painful. Usually smaller and round. | Raised growth with a rough or smooth surface, varying in size. Often flesh-colored or darker. |
| Pain | Can be painful due to pressure on nerve endings. | Generally painless, unless they occur in areas under pressure. |
| Location | Commonly found on feet or toes, where friction is common. | Can occur on various body parts, including hands, fingers, and other skin surfaces. |
| Contagious | Not contagious. | Can be contagious, but direct contact is needed for transmission. |
| Treatment | Over-the-counter pads, wearing comfortable shoes, and removing the cause. | Medical treatments, including topical treatments, cryotherapy (freezing), or laser therapy. May require multiple sessions. |
| Removal | Corns can be removed but may recur if the cause persists. | Warts can be removed, but recurrence is possible due to the nature of the virus. |
| Spread | Do not spread easily to others or different parts of the body. | Can spread to other parts of the body by self-inoculation. Can be spread to others through direct contact. |
| Complications | Infection can occur if the corn is not properly treated. | Generally benign, but some warts can become painful or bothersome if left untreated. |
| Medical Advice | If painful or causing discomfort, seek medical advice. | Medical advice is recommended, especially for persistent or painful warts. |
| Prevention | Wearing properly fitting shoes and avoiding repetitive actions that cause friction. | Avoiding direct contact with warts and keeping skin healthy to reduce susceptibility. |
What are Corns?
Corns are small, circular areas of thickened skin that develop on the feet, usually on the tops of toes or on the soles of the feet. Corns are caused by repeated pressure or friction on the skin. This pressure or friction can be caused by ill-fitting shoes, walking barefoot, or any other activity that causes repeated rubbing or pressure on the skin.
Corns can be painful and uncomfortable, and they can also make it difficult to walk or wear shoes. Corns can be either hard or soft, depending on their location on the foot. Hard corns usually develop on the tops of toes or on the sides of the feet, while soft corns usually develop between the toes.
Symptoms of Corns
The symptoms of corns can vary depending on their location on the foot and whether they are hard or soft. Some common symptoms of corns include:
- Thickened, rough skin
- Pain or tenderness when pressure is applied to the area
- A circular raised area of skin with a hard center (for hard corns)
- A circular raised area of skin with a soft, white center (for soft corns)
Causes of Corns
Corns are caused by repeated pressure or friction on the skin. Some common causes of corns include:
- Ill-fitting shoes
- High heels
- Walking barefoot
- Abnormal foot structure
- Activities that cause repeated rubbing or pressure on the skin
Treatment of Corns
There are several treatments for corns, including:
- Padding or cushioning the area with moleskin or other padding
- Wearing shoes that fit properly and do not cause pressure on the affected area
- Using over-the-counter corn removal pads or solutions that contain salicylic acid
- Soaking the feet in warm water to soften the skin before using a pumice stone to gently remove the thickened skin
- Visiting a podiatrist for more severe cases, who may recommend custom orthotics or surgery to correct foot structure issues
Note that while corn removal solutions are available over the counter, it is important to use them properly and avoid damaging healthy skin. It is also important to not try to cut or shave off corns at home, as this can lead to infection and other complications.
What are Warts?
Warts are small, fleshy growths on the skin that are caused by a viral infection. Warts can appear anywhere on the body, including the feet, but they are most commonly found on the hands and feet. Warts are caused by the human papillomavirus (HPV), which is highly contagious.
Warts can be flat or raised, and they can vary in size and shape. Warts on the feet are known as plantar warts and can be very painful due to their location on the sole of the foot.
Symptoms of Warts
Warts on the feet can be painful and uncomfortable. Some common symptoms of warts include:
- Small, fleshy growths on the skin
- Rough, bumpy texture
- Black dots in the center of the wart (which are actually blood vessels)
- Pain or tenderness when pressure is applied to the area
Causes of Warts
Warts are caused by the human papillomavirus (HPV), which is highly contagious. HPV is spread through direct contact with the virus, either by touching a wart or by touching a surface that has been contaminated with the virus. Some common causes of warts include:
- Touching a wart on another person
- Touching a surface that has been contaminated with the virus, such as a locker room floor or shower
- Walking barefoot in public places where the virus may be present, such as a public pool or gym
Treatment of Warts
Warts can be more difficult to treat than corns, as they are caused by a viral infection. Some treatments for warts include:
- Over-the-counter wart removal solutions or pads containing salicylic acid
- Cryotherapy, which involves freezing the wart with liquid nitrogen
- Laser treatment, which involves using a laser to destroy the wart
- Surgical removal of the wart
While over-the-counter wart removal solutions may be effective, use them properly and avoid damaging healthy skin. Also don’t try to cut or shave off warts at home, as this can lead to infection and other complications.
Prevention of Corn and Wart
While corn and wart can be treated, it is always better to prevent them from developing in the first place. Some tips for preventing corns and warts include:
- Wearing shoes that fit properly and do not cause pressure on the feet
- Avoiding high heels or other shoes that put pressure on certain areas of the feet
- Wearing socks with shoes to absorb sweat and reduce friction
- Keeping the feet clean and dry, especially in public places like pools or gyms
- Avoiding direct contact with warts or surfaces that may be contaminated with the virus
Who’s at risk for a wart or a corn?
Anyone can develop a corn or a wart, but certain factors can increase the risk of developing these conditions.
Risk factors for developing corn include:
- Wearing ill-fitting shoes or shoes with high heels or narrow toe boxes
- Engaging in activities that put pressure on the feet, such as running or dancing
- Having a foot deformity, such as hammertoes or bunions
- Having a gait abnormality that puts pressure on certain areas of the feet
- Having dry skin or calluses on the feet
Risk factors for developing wart include:
- Direct contact with the human papillomavirus (HPV), which is the virus that causes warts
- Having a weakened immune system, which makes it easier for the virus to take hold
- Engaging in activities that increase the risk of exposure to the virus, such as walking barefoot in public places like locker rooms or swimming pools
- Having a cut or abrasion on the skin, which provides an entry point for the virus
Note: While anyone can develop a corn or a wart, taking steps to reduce the risk factors can help prevent these conditions from developing. For example, wearing properly fitting shoes and avoiding direct contact with contaminated surfaces can help reduce the risk of developing corns and warts.
Conclusion
Corns and warts are two different conditions that can cause discomfort and pain on the feet. Corns are caused by pressure or friction on the skin, while warts are caused by a viral infection. Both conditions can be treated, but it is important to use proper treatment methods and avoid damaging healthy skin. Prevention is always the best approach, so it is important to take steps to prevent corns and warts from developing in the first place by wearing properly fitting shoes, keeping the feet clean and dry, and avoiding direct contact with warts or contaminated surfaces. If you are unsure if you have a corn or a wart, or if you have a severe case of either, it is important to consult a healthcare professional for proper diagnosis and treatment.
Frequently Asked Questions
Can I use wart remover on a corn?
No, it is not recommended to use wart remover on a corn. Wart removers contain salicylic acid, which can be too harsh for the delicate skin on the feet and can cause irritation or even injury. Instead, corns can be treated with over-the-counter corn pads or by visiting a podiatrist for more severe cases.
How can you tell the difference between a corn and a plantar wart?
Corns typically have a central core of hardened skin and are usually located on weight-bearing areas of the feet, while plantar warts have a rough, bumpy surface and may have small black dots. Additionally, plantar warts may cause pain or discomfort when squeezed from the sides, while corns are typically tender to the touch.
What is the difference between a wart, a corn, and a callus?
Warts are caused by a viral infection and are characterized by raised, rough, bumpy growths with small black dots. Corns are caused by pressure or friction and are characterized by thickened, hardened skin with a central core. Calluses are also caused by pressure or friction and are characterized by a thickened area of skin without a central core.
Is a corn or a wart painful?
Corns can be painful, especially when pressure is applied or when wearing tight or ill-fitting shoes. Warts are typically painless, but can become painful if located in a weight-bearing area or if irritated.
How do you remove a corn?
Corns can be removed by soaking the affected foot in warm water, using a pumice stone to gently exfoliate the hardened skin, and applying a moisturizer to prevent further dryness. In more severe cases, a podiatrist may use a scalpel or other medical instruments to remove the corn.
How long do warts last?
The length of time a wart lasts can vary, but warts can often persist for months or even years without treatment. In some cases, warts may go away on their own, but it is generally recommended to seek treatment to avoid spreading the infection or developing complications.
What happens if a corn is left untreated?
If a corn is left untreated, it can become more painful and may lead to complications such as infection. Additionally, if the underlying cause of the corn is not addressed, it is likely to recur.
Do warts go away on their own?
In some cases, warts may go away on their own over time, but it is generally recommended to seek treatment to avoid spreading the infection or developing complications. Treatment options may include over-the-counter wart removal solutions, cryotherapy, laser treatment, or surgical removal.
