Warts often don't respond to condylox, Aladara, and podophyllin. I suggest you get them burned off or frozen off. Warts often recur, but not right away--but you aren't removing them, just scraping off the top. Please stop doing that.
As to misdiagnosis, if the doctor has any doubt, have him send oe of the specimens he removes to the pathologist for confirmation.
Take care.
