Common skin warts often appear as raised and rough spots on the surface of your skin, and usually grow on your hands. You can also get flat warts and plantar warts, which look different than common warts:
Flat warts
Flat warts are smooth, pink, and usually smaller than other types of warts. They appear on your face, hands, and shins in large numbers. Flat warts are less common than other types of warts.
Plantar warts
Plantar warts have a rough, spongy surface. They usually develop on the soles of your feet, sometimes clustered together. Plantar warts can also have dark spots inside them.
