Case report. Onychomycosis due to Chaetomium globosum successfully treated with itraconazole

We have experienced a case of toenail infection caused by Chaetomium globosum which we treated with itraconazole 100 mg day-1 for 6 months, after which time the nail lesions were almost cured. Our case is the first reported case of onychomycosis caused by Ch. globosum in Japan, and the seventh in the world.
