Synopsis

This summary discusses adult patients. Molluscum contagiosum in children is addressed separately.

Molluscum contagiosum is a viral skin infection caused by a DNA poxvirus. It manifests as smooth firm papules with a central umbilication. Genital lesions are most commonly spread by sexual contact, and tend to be located on the hair-bearing regions of the mons and inguinal creases.

Molluscum contagiosum may also be spread by direct contact (most often in children) and autoinoculation. Infections have also been associated with swimming pool facilities via fomites.

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.

Consider underlying immunodeficiency, such as human immunodeficiency virus disease, in patients with widespread disease or large, atypical papules and/or plaques.
