Molluscum contagiosum appears as small, bead-like lesions, with a depressed center. They are benign and common in children. They are caused by viruses and as their name indicates, they are contagious, both from one part to another of the same child as well as between children. Molluscum contagiosum is always benign; even if the lesions spread, they heal independently without leaving a scar. This should be considered when treating them. It is usually pointless to remove them "aggressively".
