Plantar Warts (cont.)

Plantar Warts Causes

The HPV type 1 causes most plantar warts. The virus gains access to the skin through direct contact. It is presumed that inoculation of the skin occurs in places likely to be contaminated by others with plantar warts, like communal showers. Once infected by HPV, spontaneous resolution seems to depend on the development of immune lymphocytes that destroy the virus-infected cells. It appears that the levels of neutralizing antibodies in the blood induced by vaccination with HPV proteins can protect against certain types of genital viral infections.

Plantar Warts Symptoms and Signs

  • Foot pain localized to a thickened area on the sole
  • Firm, warty (rough, bumpy, and spongy, some appear thick and scaly) lesions with tiny pinpoint dark spots inside (not always apparent): These dark spots are minute, thrombosed (containing blood clots) capillaries in the deeper layers of the skin.
  • Smooth surface with a gray-yellow or brown color
  • Located over areas of pressure or bony point such as the heel and ball of the foot
  • Usually flat because of pressure
  • Several warts may fuse to form mosaic warts.
