What treatment modalities have you had success with for treating extensive molluscum in the pediatric population?

I've had very good success with the use of oral cimetidine, 400 mg PO tid in children. Usually, they remain on this tx for 4-6 weeks with sig clearing beginning by the 1st 2-3 weeks. I also use tretinoin gel 0.1% qd-bid to the more stubborn lesions if necessary.
