Onychomycosis due to Chaetomium globosum with yellowish black discoloration and periungual inflammation
نویسندگان
چکیده
Onychomycosis is usually caused by dermatophytes, although also other filamentous and yeast-like fungi are associated with nail invasion. Chaetomium is 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 by Chaetomium 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.

Onychomycosis Caused by Chaetomium globosum
Onychomycosis is usually caused by dermatophytes, but some nondermatophytic molds and yeasts are also associated with invasion of nails. The genus Chaetomium is a dematiaceous nondermatophytic mold found in soil and plant debris as a saprophytic fungus. We report the first Korean case of onychomycosis caused by Chaetomium globosum in a 35-year-old male. The patient showed brownish-yellow discol...
متن کاملUnusual Cause of Onychomycosis, Chaetomium globosum, in a Hilly State of North India: A Case Report
Onychomycosis, the fungal infection of nail is a common occurrence. The conventional fungi implicated are dermatophytes and Candida species. Non-dermatophytic moulds account for few cases and Chaetomium globosum is an exceptional agent. This characteristically involves the toe nails which are dystrophic and discoloured yellow-brown. Direct microscopy shows brown septate hyphae. Isolate is rapid...
متن کاملOnychomycosis Due to Nondermatophytic Molds
BACKGROUND Although there have been many studies about onychomycosis due to nondermatophytic molds (NDM), few studies about etiologic agents including NDM in onychomycosis have been reported in Korea. OBJECTIVE This study investigated onychomycosis due to NDM in the Gyeongju area of Korea. METHODS In the 10-year period from 1999~2009, we reviewed 59 patients with onychomycosis due to NDM. T...
متن کاملMolecular characterization of Chaetomium species using URP-PCR
Chaetomium spp. are common colonizers of soil and cellulose-containing substrates. Seventeen isolates of Chaetomium spp., which included 15 isolates of C. globosum and one each of C. reflexum and C. perlucidum, were genetically characterized with universal rice primers (URP primers derived from DNA repeat sequences in the rice genome) using polymerase chain reaction (URP-PCR). Out of the 12 URP...

Chaetomium globosum, the type species of the genus, is ubiquitous, occurring on a wide variety of substrates, in air and in marine environments. This species is recognised as a cellulolytic and/or endophytic fungus. It is also known as a source of secondary metabolites with various biological activities, having great potential in the agricultural, medicinal and industrial fields. On the negativ...
