Molluscum contagiosum is a flesh-colored or white, smooth, waxy papule caused by pox virus infection of the skin. Molluscum contagiosum is usually less than 0.5 cm in diameter with a small central umbilicus. The causative virus is contagious. It can be transmitted by direct skin contact and is more common in children. It is sexually transmitted and can cause genital lesions in adults. Molluscum contagiosum can infect any part of the body. The lesions are painless and itchy and are often found incidentally during a physical examination. However, when the body suppresses the virus, the lesions can appear as a reddened, itchy rash that looks like a boil. Inflammation means that the lesions disappear immediately. Most molluscum contagiosums disappear within 1-2 years, but can last for 2-3 years. Treatment is usually not needed unless they are disfiguring or cause other annoyance. The growths can be removed by freezing or with tweezers or a scraping spoon. Sometimes doctors can apply trichloroacetic acid or zebra mussels to the affected area. Topical retinoids or imiquimod cream can also be used for a few weeks to a few months.
