Warts are small skin growths that occur when the skin is infected by a virus. Although warts can occur anywhere on the body, they commonly appear on the bottom (plantar side) of the foot. Plantar warts are caused by direct contact with human papillomavirus (HPV). Plantar warts are most common in children, adolescents, and the elderly. The two types of plantar warts are solitary warts and mosaic warts. Mosaic warts appear in clusters while solitary warts appear as satellite formations. Symptoms can include thickening of the skin, pain, and tiny black dots (which are dried blood contained in the capillaries). Some plantar warts clear up on their own, while others can be removed using topical or oral treatments, laser therapy, cryotherapy, acid treatment, and surgical removal.
“Even though there are a multitude of folk remedies for warts, many are unproven and may be dangerous. Patients should never try to remove warts themselves as they may cause more harm than good.”
