Wart in a 9 y.o. girl

The patient is a healthy 9 year-old girl.  Her pediatrician referred her for a two-year history of a wart on the right middle toe after the child could not tolerate cryosurgery.
On questioning, the child states that the wart rarely bothers her.  She can walk and run without discomfort. 

My advice was to leave it alone as it will probably regress over time.  I discussed how this occurs with the girl and her grandmother.

Would you treat this?  And if so, how?

Rwecalcitrant Warts

The patient is an 11 yo girl with difficult-to-treat warts present for 4 years.  Her pediatrician has used cryotherapy, and a vesicant.  They have tried salicylic acid under occlusion for a month and the warts have grown.

The child is very self-conscious.  What would you do?
