Skin growths caused by Human Papillomavirus. Though warts are usually skin colored and feel rough, they can also be smooth, flat, and dark. The appearance may depend on where it is located on the body.

Types include:

  • common warts  – usually located on fingers and hands
  • foot (Planter) warts
  • flat warts

Warts may be passed on from person to person. These viruses occur more frequently if the skin has been damaged (i.e., biting nails). Typically self-limiting, warts may disappear without treatment over months or years. Treatment is reserved for cases that are painful, infected, or rapidly multiplying. Approaches include covering with duct tape, OTC salicylic acid preps, cryotherapy, electrosurgery, and lasers.

Dermatologist referrals for:

  • suspicion that growth is not a wart
  • wart on face or genitals
  • many warts
  • warts that hurt, itch, burn, or bleed
  • a weakened immune system
  • diabetes
