A plantar wart also known as veruca, myrmecia and veruca plantaris is a wart caused by the human papillomavirus (HPV) occurring on the sole (Latin planta) or toes of the foot. HPV infections in other locations are not plantar; see human papillomavirus.  Plantar warts and palmer warts are noncancerous skin growths, caused by a viral infection in the top layer of the skin. The culprit is a strain of virus called human papillomavirus or HPV. Many strains of the virus exist, and those that cause common warts on the hands and feet are not the same strains of HPV that cause genital warts. Some people mistakenly think plantar warts or palmer warts are malignant. In fact, they are not harmful.  The human papillomavirus (HPV) strains that are most often the cause of plantar warts are type 1 & 2 HPV. These strains are contagious and are spread from person to person via direct contact with the virus. The HPV that causes plantar warts thrives in warm, moist environments such as shower rooms and summer pool decks. Plantar warts. Sometimes painful and very ugly, plantar warts appear as small lesions on the sole of the foot, and occasionally the toes. In their early stages they look like small black puncture marks, but as they grow they turn brown and take on a cauliflower-like appearance.

They tend to grow slowly and can eventually penetrate deep enough into the skin to cause discomfort or pain. Plantar Warts Overview. Patient Comments Read 34 Comments Share Your Story.
