What Are the Different Types of Warts?

There are five different types of warts, including common warts, flat warts, plantar warts, filiform warts and periungual warts, according to Healthline. Warts are a skin growth caused by the human papillomavirus, according to WedMD.

Common warts usually grow on fingers and toes. They have a rough, grainy appearance and a rounded top. Plantar warts grow on the soles of feet. Unlike other warts, plantar warts grow into the skin, not out of it. Flat warts typically grow on the face, thighs and arms, claims Healthline.

Flat warts have a flat top and can be pink, brown or yellow in color. Filiform warts grow around the mouth and nose, and are the color of the skin, while periungual warts grow under and around the toenails and fingernails. Most warts go away on their own in a few months or years.
