Warts are raised bumps on your skin caused by the human papillomavirus (HPV). Warts have plagued humans for thousands of years — they have been discovered on 3,000-year-old mummies and were mentioned by Shakespeare. Although warts are generally not dangerous, they are ugly, potentially embarrassing, contagious, and they can be painful.

What are the types of warts?

There are five major types of warts. Each type appears on a different part of the body and has a distinct appearance.

Common Warts

Common warts usually grow on your fingers and toes but can appear elsewhere. They have a rough, grainy appearance and a rounded top. Common warts are grayer than the surrounding skin.

Plantar Warts

Plantar warts grow on the soles of the feet. Unlike other warts, plantar warts grow into your skin, not out of it. You can tell if you have a plantar wart if you notice what appears to be a small hole in the bottom of your foot that is surrounded by hardened skin. Plantar warts can make walking uncomfortable.

Flat Warts

Flat warts usually grow on the face, thighs, or arms. They are small and not immediately noticeable. Flat warts have a flat top, as if they have been scraped. They can be pink, brownish, or slightly yellow.

Filiform Warts

Filiform warts grow around your mouth or nose and sometimes on your neck or under your chin. They are small and shaped like a tiny flap or tag of skin. Filiform warts are the same color as your skin.

Periungual Warts

Periungual warts grow under and around the toenails and fingernails. They can be painful and affect nail growth.There are five major types of warts. Each type appears on a different part of the body and has a distinct appearance.
