Plantar warts are noncancerous skin growths on the soles of the feet caused by the human papillomavirus (HPV). These warts are typically found on the pressure points of the foot, such as the heel or the ball. They can appear as a small, rough lesion on the skin or as a cluster resembling a cauliflower with tiny black pinpoints, which are small, clotted blood vessels. Plantar warts can cause discomfort or pain, especially when walking. They are contagious through direct contact and can spread to other areas of the foot or to other individuals. Treatment options vary from over-the-counter remedies to professional medical procedures aimed at removing the wart.
