Plantar Warts Topic Guide
Plantar Warts: Plantar warts are painful warts on the sole of the foot. They are caused by human papillomavirus (HPV). Symptoms and signs of plantar warts include foot and leg pain and flat, firm, warty lesions with pinpoint dark spots on the sole of the foot. Treatment may involve applying moleskin around the wart and applying salicylic acid directly to the wart.
Corns and Calluses A callus (tyloma) is an area of skin that thickens after exposure to repetitive forces in order to protect the skin. A callus may not be painful. A corn is a callus with a mass of dead cells in its center. Treatment may involve cutting off the hardened skin, applying antibiotics, and using orthotics.
