FUSARIUM ONYCHOMYCOSIS

Introduction. A 69-year-old man with an uneventful past history consul ted for a proximal subungueal leukonychia and associated paronychia of the right greater toe. Macroscopic examination and culture lead to th e diagnosis of Fusarium oxysporum. Local treatment with bifonazol and cyclopirox was effective. Discussion. Fungal onychomycoses are uncommo n and usually present as superficial leukonychia. The association of a proximal localization with paronychia would suggest possible Fusarium infection. Though no specific treatment protocol is well-established, this case emphasizes the importance of effective treatment since inva sive fusariosis is described in immunosuppressed patients with ungueal localizations can be an important portal for infection.
