It's a common scenario. A mother brings in a young child with a number of (usually) asymptomatic bumps on the torso, extremities, or face. Often, they know the diagnosis, sometimes not. These are molluscum contagiosa, a common, benign, self-limited viral infection of children. For a brief overview, go to DermNet
It is our feeling that these lesions are vastly over-treated. The disease poses no threat to the child, the therapies can be painful or can take weeks to months, and the disorder runs its course over time. It is likely that if one lets nature take her course life-long immunity ensues. Aggressive therapy may prevent this and set the scenario for molluscum to recur when a child becomes sexually active. At that time, molluscum are more psychologically troublesome.

You may feel differently and want your child treated. This is your decision and you should discuss your goals with your pediatrician or dermatologist.
