Toenail infection by Cladophialophora boppii.
Cladophialophora boppii is a black yeast-like fungus that up to now has been only rarely described as a cause of human infection and whose role as a pathogen was not established despite its repeated isolation and genetic identification in these reports. Here we report the first case of a verified toenail infection caused by this fungus in a woman without any systemic disease or evidence of immunodeficiency. Identical dark molds were isolated from the same toenail at three points of time. Species identification was performed by scrutinizing the isolates morphologic, physiologic and genetic characteristics which resulted in their identification as Cladophialophora boppii. Oral treatment with terbinafin plus topical ciclopiroxolamine was effective.
