Abstract

The recently described genus Amesia encompasses four species but only Amesia atrobrunnea (=Chaetomium atrobrunneum) is known to be pathogenic to humans. Here, we describe a case of subcutaneous phaeohyphomycosis in Kuwait in an apparently immunocompetent patient diagnosed by direct microscopy of the infected tissue and culture. The identity of A. atrobrunnea was established by typical morphological characteristics and by sequencing of internally transcribed spacer (ITS) region and D1/D2 domains of rDNA. To the best of our knowledge, this is the first report documenting etiologic role of this species in causing a locally invasive subcutaneous infection.
