1. Plantar warts are often confused with calluses.
Many people mistakenly believe that any thickening of the skin on the foot is simply a callus. However, this belief can easily lead to misunderstandings. A condition commonly called a plantar wart may look very similar to a callus at first glance, but it is actually a different skin problem. While both can appear as areas of thickened skin, their causes, development, and treatments are different.
A plantar wart is not just a minor cosmetic issue or an irritation caused by shoes. In medical terms, it is a viral lesion on the sole of the foot that can cause pain when walking, persistent discomfort, and sometimes difficulty putting weight on the foot. For these reasons, it is important to understand the origin of plantar warts and how to distinguish them from common calluses to avoid incorrect treatment.
2. Causes and Signs That Help Identify Plantar Warts
Calluses form naturally when the skin thickens in response to repeated friction or pressure, usually caused by tight shoes or constant rubbing. Plantar warts, on the other hand, are caused by the human papillomavirus (HPV). This virus can enter the body through small cuts, cracks, or weakened areas of the skin. Once inside, it stimulates abnormal skin growth, producing the wart.
Since plantar warts are viral infections, under certain conditions they can spread to other parts of the foot or even to other people. Warm, humid environments, such as swimming pools, locker rooms, gyms, and public showers, increase the risk of infection, especially when walking barefoot.
