Molluscum contagiosum is a common viral skin infection that causes localized clusters of bumps of the skin. They often have a waxy, shiny look with a small central pit (this appearance is described as umbilicated). It mainly affects children and young adolescents but rarely can also be found on adults. This is because most adults’ immune systems are able to fight off the virus before it can infect the skin. Molluscum contagiosum tends to be more numerous and last longer in children who also have atopic dermatitis (aka eczema), due to deficiencies in the skin barrier. There may be few or dozens of bumps on one individual. They mostly arise in warm moist places, such as the armpit, behind the knees, groin or buttocks. The lesions are harmless, but some complications may include a secondary bacterial infection or a secondary dermatitis due to scratching. These can be easily treated with an antibiotic and a mild topical steroid cream.
What causes Molluscum Contagiosum?
Molluscum contagiosum is caused by the poxvirus. When the bumps are present, the virus is easily transmissible and can spread through a variety of manners such as direct skin to skin contact, indirect contact via sharing towels, or spread on one’s own body via scratching. Transmission of molluscum contagiosum appears to be more likely in wet conditions, such as when children bathe or swim together.
What is the treatment for Molluscum Contagiosum?
Most of the time molluscum can easily be treated with either a topical solution called Cantharidin or by cryotherapy (aka freezing). Sensitive areas such as on the face may also be treated with a mild topical retinoid. Complications from treatment are rare and mild and is usually irritation that quickly resolves with a mild topical steroid.
