Is there acid that dissolves it ?

I don't believe so; even the strongest known acid (fluoroantimonic acid) can be held in teflon containers. That doesn't mean that teflon is impervious to chemical attack, however. Hot fluorine gas and some alkali metals will react with it.

Here are some notes of using Sodium naphthalenide (http://en.wikipedia.org/wiki/Sodium_naphthalenide) which is a strong base to etch (defluorinate) teflon.

However, I think it only alters the outer layer of the teflon.
