Warts

 

Warts are skin growths caused by the human papillomavirus (HPV).

They are most common on the hands and feet, but can be seen almost anywhere on the body.

Warts are contagious, and can spread on the skin and even to other people. For this reason, it is important to see a board-certified dermatologist early to initiate treatment.

What are different types of warts?

There are over 100 types of HPV, each causing slightly different presentations of warts. These include:

  1. Common warts: rough warts most often on the hands and fingers

  2. Plantar warts: flat, hard warts on the bottom of the feet, often with black dots

  3. Flat warts: small, smooth warts that cluster in large numbers, most common on the face and legs

  4. Filiform warts: thin, thread-like warts most common on the face

  5. Genital warts: smooth to warty bumps on the genitalia

How are warts treated?

Warts are transmitted through direct contact with a wart or through touching something that came into contact with the wart. Therefore, it is important to avoid touching the warts or shaving over them. Warts can be difficult to treat, and often requires multiple treatment sessions. These therapies include:

  • Topical salicylic acid and 5-fluorouracil

  • Liquid nitrogen (cryotherapy)

  • Cantharidin application

  • Electrodessication

  • Shave excision

  • Intralesional candida antigen or bleomycin

  • HPV vaccination

  • Oral zinc or cimetidine
