Molluscum contagiosum is a common viral skin
infection caused by the poxvirus, leading to clusters of smooth, round bumps
that often appear shiny or waxy. These bumps are typically small and feature
a central indentation (called umbilication).
The condition primarily affects children and young
adolescents, particularly those with atopic dermatitis (eczema), which can
impair the skin’s barrier and allow the virus to spread more easily. In rare
cases, adults may also be affected—usually if their immune system is
compromised.
Molluscum tends to form in warm, moist areas like the
armpits, groin, behind the knees, or on the buttocks, and may appear singly
or in large clusters. Though the lesions are harmless, complications can
occur due to scratching, including secondary bacterial infections or skin
irritation, which are generally mild and treatable.
The virus is highly contagious and spreads through
skin-to-skin contact, sharing towels, or self-inoculation via scratching. Wet
environments, such as bathing or swimming, may increase transmission risk
among children.
In many
cases, molluscum resolves on its own within 6–12 months. However, treatment may
be recommended to reduce spread or irritation.
The most common therapies include topical
Cantharidin, a solution that causes the bumps to blister and fall off, and
cryotherapy (freezing). On delicate areas such as the face, a mild topical
retinoid may be used. Post-treatment irritation, if present, typically responds
well to a mild topical steroid. Providers at Charlotte Dermatology will assess
