Warts are growths on the skin caused by Human Papilloma Virus (HPV). Warts are round or oval shaped, varying in size from few millimeters to few centimeters. They are usually asymptomatic, but sometimes, may be associated with pain and / or itching. The most common areas of the body affected include hands, feet, face, forehead and genital areas.
They are usually harmless, however can be disfiguring and embarrassing, and occasionally they itch or hurt (particularly on the feet). An important fact about warts is that they are infectious and have a tendency to spread locally and from one body part to another, and also from one person to another. They can be of various types like common warts, filiform warts, plane warts, and plantar warts.
Warts are usually treated precisely by ablative CO2 laser or radiofrequency (RF) ablation. The procedure is required to be done under anesthesia, either topical or local injectable, depending on the number of lesions and depth of lesions. Wart removal is usually a single session treatment.
There occurs crust formation 2-3 days post procedure, which then falls off on its own in next 5-7 days. So it takes around 7-10 days in total for complete recovery of the skin. It is advisable not to pick the crusts to prevent scar formation. Superficial lesions do not leave any scar. However, deeper lesions may leave faint superficial scars.
Once treated adequately, the results are permanent, however, in some individuals, warts may recur and may require two or more treatment sessions.
