Generally, four types of warts are seen, including: Ordinary (Common):Ordinary warts are seen as small bumps with very rough skin. These are found mostly on hands but can also appear on any part of the body, including fingers, feet, and knees. Flat: Flat warts are flatter, smaller, and smoother than other warts. These usually painless warts are common in children and teens and likely to appear in clusters on face, back of the hands, and legs. Plantar: These light brown-coloured warts appear on the soles (plantar surfaces) of the feet or toes. Plantar warts do not grow outward like other warts and can also have tiny black dots in them. Genital:These painful warts occur in the genital area with light pink or red dots and may even bleed. Genital warts are transmissible via sexual intercourse and grow quickly with an intense desire for itching.
