What are the differences between corns and common warts

Common warts are a common skin disease. Because their appearance and symptoms are somewhat similar to corns, some patients may make mistakes when making their own judgments and treatments. From a mechanistic perspective, corns are caused by long-term friction, while common warts are caused by viral infection.

Corns have a smooth surface, which is level with the epidermis or slightly raised, with clear boundaries, and are light yellow or dark yellow in color. They are slightly transparent, and the tip is wedge-shaped and embedded in the dermis. A layer of grayish-white film, the corn bursa, can be seen underneath. Feeling pain when walking under pressure. Common warts are gray-brown, brown or skin-colored papules with a rough surface and hard texture, and may have papilloma-like proliferation.

As for common warts, they are epidermal tumors caused by human papillomavirus, which are called "thousand-day sores" in traditional Chinese medicine and commonly known as "thorn warts", "fish rust", "warts", etc. This disease is caused by human papillomavirus and is transmitted through direct or indirect contact. Trauma is a very important factor in human papillomavirus infection.

Therefore, warts are caused by viral infection, not by blood disease. However, the occurrence of this disease is related to the body's immune status. The incidence of warts increases in people with immunodeficiency. Generally speaking, corns are caused by long-term pressure or friction, while common warts are caused by viruses.
