Cutaneous phaeohyphomycosis caused by Amesia atrobrunnea. Phaeohyphomycosis

A case of cutaneous phaeohyphomycosis caused by Amesia atrobrunnea (= Chaetomium atrobrunneum) in an apparently immunocompetent patient is described. The identity of A. atrobrunnea was established by typical morphological characteristics and by sequencing of internally transcribed spacer (ITS) region of rDNA and partial sequencing of β-tubulin gene fragment. This is the first report documenting pathogenic potential of this species causing locally invasive infection.
