Synopsis

Molluscum contagiosum is a viral skin infection caused by a DNA poxvirus. It manifests as smooth firm papules with a central umbilication. Molluscum contagiosum may be spread by direct contact (most often in children), autoinoculation, or via sexual transmission in adults. Molluscum contagiosum infections have also been associated with swimming pool facilities via fomites.

In adults, molluscum contagiosum is more commonly distributed on the mons pubis, the genitalia, perineum, inner thighs, and lower abdomen. The distribution in children is trunk and extremities.

Many cases are asymptomatic, but there can be surrounding irritation in association with pruritus. Molluscum may occur in tattoos.

Papules may persist for several months and up to 2 years before disappearing. In the immunocompetent host, the disease tends to be self-limited.

Patients with AIDS or who are otherwise immunosuppressed are at particular risk of molluscum infection, with prevalence rates of 5%-18% having been reported. Other risk factors are atopic dermatitis and sarcoidosis.
