There was a question about the lesion on her nose - most of us have dealt with lesions as well. Since the oral azole drugs are systemic and are already treating the infection from the inside, there's not a lot of need for topical treatments. That's good, because we don't really know of any that are specifically for a hardcore fungus like blasto.
To make ourselves feel better, and as though we were actually doing something to help, many of us have used topical antifungal creams on the lesions. Our experience is mostly anecdotal. Whether they work on their own or not is debatable, but they may actually help. (Although on a nose, I'm not sure how happy she'd be.)
These are available OTC from drug stores crowded with people who all know you, and they usually say lots of things about Jock Itch or Feminine Itching in bright red capital letters that can be seen from a great distance. Make sure to purchase an assortment; it enables you to part a crowd like the Red Sea.

Seriously, Dirt's first lesions were disgusting, and they seemed to respond a bit to creams. Neosporin can't treat them, so an azole can't hurt. Anti-dandruff shampoos also contain antifungal medications (Diflucan, Nizoral, Ketoconazole) and may help heal sores that may be hiding under the fur. Wilson3 has great advice on agressive treatments for large areas as well.
Definitely keep using the internet. It may not be the greatest resource for every single thing, but for Blasto - (pardon me) but many vets are woefully uneducated.
We've seen too many animals lost to a lack of knowledge, delayed or missed diagnoses, wrong dosages, use of improper treatments, people not being told how to give medication, not having an affordable source for meds, you name it. Find out all you can, and share it with your vet.
