Skin tags are not the same as corns; they are two completely different conditions. Skin tags generally refer to abnormally proliferating tissue at the nail area, and also commonly refer to warts. Corns usually result from localized abnormal friction, causing proliferative growth of the soft tissue, typically located on the sole of the foot. Skin tags and common warts can also occur on the bottom of the feet, but skin tags usually appear as proliferative, tumor-like protrusions on the surface of the skin, whereas corns generally do not protrude above the surface of the skin.

The difference between plantar warts and corns

Toe warts and corns are both skin diseases that occur on the feet, but they are entirely different diseases, and many people easily confuse toe warts with corns. First, the causes of toe warts and corns are different. The occurrence of corns is greatly related to compression and friction, while toe warts are mainly caused by viral infections due to reasons such as low immunity. Secondly, their contagiousness is different; corns are not contagious, while toe warts are highly contagious.

What causes corns on the soles of the feet?

Corns are mostly caused by the prolonged and repeated friction and compression of a foreign object that has entered the skin, resulting in a hyperproliferative lesion. They are generally small and can be completely treated with common corn ointments. However, if a corn has been present for a long time and has grown larger, it is recommended to seek treatment at a formal hospital's dermatology department using the method of liquid nitrogen freezing, which usually resolves the issue in one or two sessions. Some corns can become larger and may be painful or show signs of inflammation and infection. In such cases, it is advisable to visit a surgical or dermatology department for a minor minimally invasive surgery to completely remove it. When wearing shoes, it is essential to choose loose and soft-soled footwear, and avoid walking barefoot on surfaces to prevent foreign objects from entering and causing the recurrence of corns.

Do corns that don't hurt need to be treated?

Corns are mostly caused by the entry of foreign objects into the skin locally, followed by hyperplasia formed through repeated friction, generally appearing as wedge-shaped on the surface of the skin. If corns are not treated, they might gradually grow larger or increase in size, causing pain during long-term walking. Even if there is no pain temporarily, treatment is still necessary. It is advised to go to the dermatology department of a regular hospital for surgical removal or use liquid nitrogen freezing. This condition can be prevented from recurring by paying attention to one’s walking posture, shoe-wearing habits, and avoiding stepping on dirty things. Regular exercise to strengthen immunity and avoiding walking barefoot are also beneficial.

What is a corn like?

Corns are a common skin disease, closely related to prolonged standing or constant friction and compression under the feet. Corns consist of a hyperkeratosis forming a circular or oval, yellowish appearance. They generally cause severe pain once they develop, and prompt treatment is necessary. This can include the use of topical medications or physical therapy methods, such as laser treatment.

Can corn plaster be used on warts?

Warts, commonly referred to as corns, are caused by viral infections. This condition is somewhat related to the individual’s immune system, so physical therapy can help improve the situation. Corn plasters can be effective for treating warts, but it is essential to avoid overusing them to prevent local damage and other issues. Additionally, there are other treatment options for warts, such as laser surgery, which can effectively address the problem. Surgical removal with a scalpel or podiatry knife can also completely eradicate the wart. Adapting the treatment method based on specific changes can lead to quicker recovery; however, it is crucial to prevent any infections associated with warts.
