Molluscum contagiosum (MC), sometimes called water warts, is a viral infection of the skin that results in small raised pink lesions with a dimple in the center.[1] They may occationally be itchy or sore, and occur singularly or in groups.[1] Any area of the skin may be affected, with abdomen, legs, arms, neck, genital area, and face being the most common.[1] Onset of the lesions is around seven weeks after infection.[3] They usually go away within a year without scarring.[1]

The infection is caused by a poxvirus called the molluscum contagiosum virus (MCV).[1] The virus is spread either by direct contact, including sexual activity, or via contaminated objects such as towels.[4] The condition can also be spread to other areas of the body by the person themselves.[4] Risk factors include a weak immune system, atopic dermatitis, and crowded living conditions.[2] Following one infection, it is possible to get re-infected.[9] Diagnosis is typically based on the appearance of the lesions.[3]

Prevention includes hand washing and not sharing personal items.[6] While treatment is not necessary, some may wish to have the lesions removed for cosmetic reasons or to prevent spread.[7] Removal may occur with freezing, laser therapy, or opening up the lesion and scraping the inside.[7] Scraping the lesion can, however, result in scarring.[9] The medication cimetidine by mouth, or podophyllotoxin, cantharidin or potassium hydroxide cream applied to the skin, may also be used.[7][10]

Approximately 122 million people globally were affected by molluscum contagiosum as of 2010 (1.8% of the population).[8] It is more common in children between the ages of one and ten years old.[2] The condition has become more common in the United States since 1966.[2] Having the infection is not a reason to keep a child out of school or daycare.[11]
