Cutaneous alternariosis in an immunocompetent patient.

Alternaria species are a type of dematiaceous fungi that cause a wide spectrum of disease with cutaneous infections being the most common. These infections are most common in immunocompromised individuals. However, only a few cases of primary cutaneous alternariosis have been reported in immunocompetent patients. We present a case of an otherwise healthy 13-year-old male who presented with primary cutaneous alternariosis on his left ankle that responded to the use of topical econazole and oral itraconazole. We also provide a review of previously described cases of primary cutaneous alternariosis in the literature.
