Plantar Warts

What are warts and what causes them?

A wart is a skin growth caused by some types of virus called human papillomavirus (HPV). There are over 100 known types of HPV. HPV infects the upper skin layer and usually enters the body through broken skin area. The virus causes the rapid growth of the surface layer of the skin which gives rise to a wart. Most warts disappear on their own within months or years.

Warts can grow on any part of the body. They are most common among children and young adults.

There are five types of warts. Are different and are formed in different parts of the body.

Common warts often grow on the hands, but can appear anywhere on the body. Are rough, domed brown and gray.
Plantar warts grow on the soles of the feet. They look like patches of hard, thick skin with dark specks. Plantar warts can cause pain when walking, and you may feel like you stepped on a stone.
Flat warts usually grow on the face, arms or legs. They are small (usually smaller than the eraser on a pencil), have flat ends and can be pink, light brown or yellowish.
Filiform warts usually grow around the mouth, nose or beard area. They are the same color of the skin and have growths that look like wires sticking out of them.
Periungual warts grow under and around the nails of toes and fingers. They look like lumps with rough surface and irregular edges. They can affect nail growth.

How do warts spread?

Warts are easily spread by direct contact with the human papilloma virus. You can re-infect by touching the wart and then touches other parts of the body. Can infect others by sharing towels, razors (razors) or other personal items. After contact with HPV, can take many months of slow growth beneath the skin before you notice a wart.

It is unlikely that spreads a wart increasingly coming into contact with HPV. Some people are more prone to getting warts than others.
What are the symptoms?

Warts are presented in a wide variety of shapes and sizes. A wart may be a bump with a rough surface, or it may be flat and smooth. Small blood vessels growing in the center of the supply blood wart. In the common and plantar warts, these blood vessels can be seen as dark spots in the center of the wart. In most cases, the lines are stretched and the skin folds are on the wart.

Warts are usually painless. But a wart to grow in a place where you put pressure, like a finger or the bottom of the foot, can be painful.
How are warts diagnosed?

A doctor can usually tell if a skin growth is a wart just by looking. Your doctor may take a sample of the wart and looked at under a microscope (biopsy of skin). This could be done if it is not clear that growth is a wart. You could also do if a skin growth is darker than the surrounding skin, is an irregular patch on the skin, bleeding or is large and fast growing.
How are they treated?

Most warts do not require treatment. But if you have warts that are painful or extend, or if it bothers your appearance, your treatment options include:

Using a home treatment such as salicylic acid or duct tape ("duct tape"). These products are available without prescription.
Put stronger medicine on the wart or inject medication into it.
Freezing the wart (cryotherapy).
Remove the wart with surgery (electrosurgery, curettage, laser surgery).

Treatment of warts does not always work. Even after a wart shrinks or disappears, warts may return or spread to other body parts. This is because most treatments destroy the wart, but do not kill the virus that causes it.
