Warts are contagious skin growths caused by a virus in the skin. They are commonly seen in children and teens, though any age may be affected. Warts can appear on any area of the body, but often on the hands, feet, or face. Some warts do not require treatment; however, a dermatologist may treat warts that are stubborn, painful, or spreading. Treatment can take several months, and options include in-office application of liquid nitrogen, surgical removal, or at-home application of anti-viral medication and/or salicylic acid.
Molluscum contagiosum is a contagious bumpy rash on the skin caused by a virus. Onset may occur at any age, but is especially common among school-age children. These bumps may appear almost anywhere on the body, though most commonly in the skin folds of the underarms, back of knees, and groin. This condition is benign and does not require treatment in mild cases. A pediatric dermatologist may treat molluscum to limit spread to other areas of the body, control itching, reduce transmission to others (ex. athletes in contact sports), and minimize potential for scarring. Treatment options include in-office application of liquid nitrogen or cantharidin, surgical removal, or at-home application of anti-viral creams.
