Warts Types Filiform Periungual

Periungual warts and filiform warts are two discrete kinds of warts, with distinct appearances. They grow in different ways and various places, but they have one common cause: human papillomavirus (HPV). Different strains of HPV cause periungual warts and filiform warts.

Periungual Warts

Periungual warts grow under and around fingernails and toenails. They start out small, about the size of a pinhead, but they can grow to the size of a pea. Most resemble a cauliflower and they can be quite painful.

A growing periungual wart can cause the fingernail plate to lift and, in extreme cases, damage the nail. Despite the potential discomfort, periungual warts are considered benign.

Treating Periungual Warts

Periungual warts seem to be more common in people who bite their nails. To prevent periungual warts or control their spread, refrain from biting your nails.

HPV gets into your system through broken skin, so keeping the area around your toes and fingers clean and healthy can stop the spread of warts. Although periungual warts are spread from person to person, the most direct path of transmission is from one spot to another on your own body.

Some of the techniques you can use to get rid of periungual warts yourself include:

  • Duct tape
  • Over-the-counter wart removers
  • Salicylic acid.

If you have a stubborn case of periungual warts, or if they’re awkwardly placed, see a physician. Your doctor can use other techniques to remove them, including:

  • Electric needles
  • Freezing
  • Lasers.

Filiform Warts

Of all the types of warts, filiform warts tend to have the most unusual appearance. They’re flesh-colored, long and narrow and are sometimes described as fronds, cylinders or brushes.

Although they grow very quickly, filiform warts are benign. They’re considered variations of the common wart, and are caused by specific HPV strains, including:

  • HPV 1
  • HPV 2
  • HPV 4
  • HPV 27
  • HPV 29.

Filiform warts can grow individually or in groups around the:

  • Eyelids
  • Face
  • Lips
  • Neck.

Filiform Wart Removal

Because filiform warts generally grow on or around the face, a physician should always be consulted for filiform wart removal.

The good news is that filiform warts are generally easy to treat, and your doctor can use a variety of treatment methods including:

  • Freezing
  • Immunotherapy
  • Lasers
  • Surgery.

One of the factors to consider with surgery is the potential for scarring, so discuss your concerns with your doctor.

To prevent the spread of filiform warts, avoid sharing towels or makeup, and throw out your facial products after you discover a filiform wart.
