Warts are benign skin growths caused by the human papilloma virus. Many treatments are available for warts, the simplest being over-the-counter salicylic acid solutions and patches. In office treatments include freezing the warts with liquid nitrogen, applying a stronger medication than the over-the-counter variety, or using injections of Bleomycin. A medication may also be prescribed by your physician to boost your immune system to fight off the wart virus. Warts usually need multiple treatments for total resolution. Sometimes surgical removal is required.
Molluscum contagiosum is a skin infection caused by a pox virus. It's quite common among children, and is usually spread by skin to skin contact. In adults, the virus can also be transmitted through sexual contact. Molluscum are painless, raised papules on the skin that look like pink pearls. They frequently appear on the face, neck, arms, and chest, although they may develop nearly anywhere on the body, including the groin. The growths often have a slight indentation in the center and a round waxy core. Scratching can spread the infection, leading to lines or clusters of them on the skin. They can be successfully treated with topical medications, liquid nitrogen or surgical removal.
