Molluscum: Molluscum contagiosum virus causes a benign viral infection that is largely (if not exclusively) a disease of humans. Molluscum contagiosum virus causes characteristic skin lesions consisting of single or, more often, multiple, rounded, dome-shaped, pink, waxy papules that are 2-5 mm (rarely up to 1.5 cm in the case of a giant molluscus) in diameter. The papules are umbilicated and contain a core.
