Flat Warts: Symptoms, Causes & Treatments

Written by Dave

Flat warts are tumour-like spots that appear on the surface of the skin. They are called “flat warts” because they have flat growth and the growth resembles small nettles. Flat warts occur mostly in adolescence and childhood and that is why it is sometimes called “juvenile warts”.

This kind of warts appear on the parts of the body like the leg, neck, face, fingers and hands. Flat warts are common in the face.

What causes Flat warts?

Viruses usually cause flat warts. They are known as Human Papilloma Virus (HPV), and more than 100 strains have been identified but the leading causes of flat warts are the human papilloma virus (HPV) strains 3, 10, 28, and 49. They love a warm and moist area and that is why they inhabit the skin and mucosal surfaces.

When they find a suitable place to grow, they invade the outermost protective layer of the skin to grow, develop, and proliferate. HPV is highly contagious and transmitted via person to person contact or sometimes by touching an infected object.

Symptoms of Flat warts

Sometimes, flat wart can take up to a year for it to grow to a visible size and in this case, it may not quickly be discovered until the original infection surfaces. Flat warts are flesh -colored or whitish and slightly raised above the skin.

Flat warts usually grow or develop on the face, hands, and areas that are often shaved such as women’s legs and men’s faces. Flat warts do occur in multiples or clusters. Very rarely will you find a flat mole alone. This kind of wart is not painful, unlike some other types.

It is tough to identify since they have a similar color to that of the infected patient’s skin. One of the symptoms which can be used to determine flat wart is the small bumps that grow on the skin surface.

Other symptoms are associated with this skin condition which includes: rough growths, abnormal dark or light skin that surrounds the injury or wound (lesion), etc.

Treatment of Flat wart

Flat warts can be difficult to treat because they occur in multiples and in areas that are prone to re-infection. Treatment is not always necessary as the wart will go away after a few months as a result of the body’s immune system fighting back.

A flat wart can be treated by the use of stronger chemicals which include Salicylic acid, glycolic or retinoin which is used to remove the top layer of warts. The patients can go for Cryotherapy which freezes the tissue in liquid nitrogen.

We also have other methods which can be used to treat it which include, electro-surgery or pulsed laser beams which burn and kill warts, and by so doing, warts only drop off.

A Poisonous chemical compound called “Cantharidin” can also be used to treat this kind of wart, but it is beneficial to those having stubborn flat warts on their face.

How can flat warts spread?

Flat warts can spread through direct skin contact with the person having it. It can also spread by using the face towel of the infected patients, by shaking hands with someone that is infected with this kind of wart, and the list is endless.
