These lesions are associated with the molluscum virus and are present on a person who has a weakened immune system (immunocompromised). Molluscum contagiosum are small, raised, pearly skin lesions caused by the molluscum virus, a member of the poxvirus family. They are seen frequently in children and less often in adults. In adults, they may be considered a sexually transmitted disease. Immunocompromised individuals may experience heavy outbreaks of these lesions, as seen in this photograph.
