Molluscum contagiosum is a harmless viral infection that is more common among children than adults. It is easily transmitted by direct or nonsexual skin- to-skin contact and during sexual intercourse.
The infection produces tiny lumps (papules) that are shiny, pearly white, and circular. Each lump has a depression in the middle, which produces a cheesy ﬂuid if squeezed. A crust forms before healing occurs. Papules may appear (in groups or alone) on the genitals, inside of the thighs, on the face, or other places.
Molluscum contagiosum usually clears up by itself in a few months but may require treatment that destroys the growths with heat, cold, or chemicals.
