Plantar warts are common warts that occur on the soles of the feet. Therefore, plantar warts are a special type of common wart that occurs on the soles of the feet. Plantar warts belong to the category of common warts. Common warts are caused by the human papillomavirus (HPV), which infects the skin and mucous membranes, resulting in benign growths such as common warts, flat warts, or genital warts, among others. However, the subtypes of HPV causing these infections vary. Additionally, within common warts, those occurring on the soles of the feet are specifically referred to as plantar warts. Plantar warts mainly appear on the front part of the sole, which is an area subject to friction and often sweatier, thus making it more susceptible to warts. These warts can be painful, or they might not cause any discomfort at all.
