Case of Fusarium paronychia successfully treated with occlusive dressing of antifungal cream.

We report a case of refractory Fusarium paronychia in a 42-year-old man with Behçet's disease receiving oral cyclosporin and corticosteroid. Symptoms resembling candidal paronychia of his little finger could not be cured by topical ketoconazole and oral terbinafine. The pathogen was identified as Fusarium solani species complex by gene analysis, and was multiple drug resistant. The case eventually resolved by occlusive dressing therapy with 0.5% amorolfine cream for 3 months.
