Hole in the center due to the structure of the wart/callus
If you notice a hole in your callus, it may be more than just a regular callus. Often, what appears to be a callus with a hole could actually be a plantar wart. Plantar warts, caused by the human papillomavirus (HPV), commonly develop on the bottom of the foot and can appear similar to calluses. They sometimes have a small hole in the center due to the structure of the wart and clotted blood vessels, which can look like tiny black dots within the wart.
Unlike calluses, which are caused by repeated pressure or friction, plantar warts are viral and can spread to other parts of the body or even to other people. They can also be painful, especially when walking or standing. If you suspect your callus has a hole and might be a plantar wart, it’s best to consult a podiatrist for a proper diagnosis. Treatment options for plantar warts include salicylic acid, cryotherapy, or even laser treatment for persistent cases.
Taking steps to protect your feet, like wearing flip-flops in public showers and keeping your feet clean and dry, can help prevent the spread of plantar warts. If the hole in your callus concerns you, a professional opinion can provide peace of mind and help you find the right treatment for your condition.
