title: Onychomycosis due toChaetomium globosumwith yellowish black discoloration and periungual inflammation.
abstract: Onychomycosis is usually caused by dermatophytes, although also other filamentous and yeast-like fungi are associated with nail invasion.Chaetomiumis an environmental genus of ascomycetes exhibiting a certain degree of extremotolerance. We report the first case of onychomycosis in a 46-year-old woman in China caused byChaetomium globosum. The patient showed yellowish black discoloration with periungual inflammation on the left first toenail. We confirmed the causative agent,C. globosum,by KOH mount, culture, micromorphology and DNA sequence analysis.
