White patches on skin

[Michael Neau]

So I'm at a loss, this is my first bearded and I've had her for about a year. About 2 months ago she developed a white fuzzy spot on her neck that I originally thought was some sort of fungus. The spot has since, for lack of better term, crusted over and become like a plate. I have tried Lamisil and it has stopped growing, but wont go away. Other than excessive shedding she acts normal, eats well, interacts with me and the kids, etc. Any help would be really appreciated. And if it helps, I live in NW Florida near the Gulf of Mexico, so humidity is high.

Thanks in advance
