A wart is a viral infection caused by certain types of viruses of the human papillomavirus (HPV) family. Their main characterictic is that of a local growth on the skin that may look like a solid blister or a cauliflower. They are mostly found on the hands or feet but can also appear at other locations of the body such as the face. Most warts are harmless resulting in small cosmetic concern and often disappear within a few months but some can persist for a few years and even reoccur. Although harmless, warts are contagious and can easily affect other persons. They can often be past through areas of broken skin. Other types of warts are malignant and can lead to cancer. The most dangerous type of wart is caused by some types of HPV on the genitals increasing the risk of cervix cancer. Beside genital wart, other types of warts can be identified and classified:
1) Common Wart (verruca vulgaris)
Common warts can appear at any part of the body but are often found on hands, elbows, knees or legs. They have a rough surface which can easily be felt. Common warts are harmless but can cause some cosmetic problems especially if they appear on the face. Common warts are very contagious and can easily be transmited to another person directly or indirectly. There therapy can involve the use of cream or surgery in the most extreme case. When on visible parts of the body, they can be embarrassing and annoying.
2) Flat wart (Veruca plana)
Flat warts often affect the hands, face, legs, neck or arms. They often are of reddish-brown color appearing as a small lump on the surface of the skin. Their growth can result in a cluster formation of twenty to hundred warts. Flat warts can be transferred directly or indirectly from one person to another through cuts, cracks, abrasions or other types of skin eruptions. When diagnosed in its early stage, flat warts can be treated effectively. At a later stage if the progression results to the formation of a cluster, it can lead to a malignant tumor or cancer. The appearance of flat warts do not involve pain or any symptoms which often results in many people not seeking medical advice until it has progresssed to a more advance stage. Treatment for flat warts can be done when diagnosed early with over-the-counter products such as silver nitrate, salicylic acid, and other types of cream which usually burn the dead skin allowing the wart to fall. If the warts are large lazer treatment or surgery can often be performed and most recommended.
3) Plantar warts
Plantar warts are often found on the sole feet. The Main characteristic is a lump usually of grey, brown or yellow color with dark spots. They are often produced by a virus which often affects areas of pressure applied on the feet infecting the epidermis or outer skin layer. The wart can cause a lot of paint and hinder normal activities if located at a pressure point of the foot. They can often be encountered on different surfaces such as swimming pools, shower cubibles, or locker rooms and can enter the skin through break in the skin surface. A plantar wart virus is not highly contagious but can often take months or years to cure by themselves. Although their development can occur regardless of age, they are often noticed on children between the ages of 12 to 16 years of age.
If plantar warts are not causing discomfort to the foot, it is much better to leave them as most wiill disappear after a few months or years. There are many different treatments for plantar warts and each are not guaranteed to be effective in every case. Consideration should also be given to the fact that there is always the possibility of further develoment even if treatment is successful; some warts are very stubborn to treatment and finally, the treatment for plantar warts can be very painful. Common treatment for plantar warts includes:
+Salycylic acid – the chemical usually removes the outer layer of the wart. The treatment should be administered for at least 12 weeks every night. A good tip is to soak the wart in warm water for five minute to soften it which helps with the treatment. Application of the cream should be on the warts and exterior surrounding of the skin near the warts only.just before preceding with the application, the warts should be gently filed with sandpaper.
+ Formaldehyde preparations – this type of treatment is most effective on mosaic warts. Treatment consists of soaking the affected area for at least ten minutes in the formaldehyde solution.
+Cryotherapy – this type of treatment consists in freezing the warts using liquid nitrogen with the aid of a coton or spray. The treatment can last up to four week. Using cryotherapy to treat plantar warts is quite painful and can often cause blisters. The treatment should be administered by a trained nurse or your doctor.
+Other treatments – Some other types of treatment that are often used include occlusion therapy, the application of tea tree oil and even hypnosis and complementary medecine
+Local anaesthetic – if all the above treatment does not prove effective in removing plantar warts, consideration can be in removing through surgical procedure. It consit in scraping the wart away and then cauterizing the remaining area. Removing through surgery often leaves scars and could prove painful on the sole. It also does not prevent the wart from reappearing.
Precaution is always necessary when infected with any types of wart. Avoiding scratching can help prevent spreading the infection. It is also necessary to avoid using items of a person that is infected. Seeking medical attention especially in the case of genital warts can help determine if the infection is malignant and early treatment can often cure most cases of warts.
