Fusarium species are known as ubiquitous soil saprophytes and human skin comtaminants. Occasionally, however, they have been reported to cause a variety of infections in humans. We report herein a case of cutaneous infection by Fusarium sokmi in a patient with Burger's disease involving his right lower leg. He was treated with itraconazole 200 mg p.o. per day for 5 weeks and the skin lesion resolved without any noticeable side effects. Furthermore, there has been no evidence of recurrence of the disease 9 months after discontinuing the itraconazole. This is the first reported case of cutaneous infection by Fusarium sokmi in a patient with Burger's disease and itraconazole was an effective drug in our case.
