Blastomycosis.

Blastomycosis is an uncommon, sometimes self-healing, sometimes fatal, infectious disease caused by the fungus Blastomyces dermatitidis. Although amphotericin B is still considered the drug of choice, ketoconazole and several other imidazole drugs--miconazole, itraconazole, econazole--have shown promise in the treatment of blastomycosis.
