Unusual Cause of Onychomycosis, Chaetomium globosum, in a Hilly State of North India: A Case Report
نویسندگان
چکیده
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 rapidly growing, grey-brown mould with characteristic osteolate perithecia surrounded by brown septate setae. Perithecia discharge lemon shaped, brown ascospores. Chaetomium being a soil saprophyte may escape identification as a pathogenic agent. We describe the case of a 50 years old female with onychomycosis of toenails by Chaetomium globosum.

Onychomycosis due to Chaetomium globosum with yellowish black discoloration and periungual inflammation
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...
متن کاملOnychomycosis 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...

Heterotopic pancreas is an uncommon developmental anomaly of upper gastrointestinal tract. Heterotopic pancreas tissue is very rarely found in ileum. Intussusception in children is usually idiopathic, but definitive aetiology can be established in 90% of adult cases. We are reporting a case of pancreatic heterotopia presenting as a lead point of ileo-ileal intussusception in a 1year 3month year...

Onychomycosis refers to nail infections caused by any fungus, including yeasts and nondermatophyte molds. Fungal infection has emerged as an important cause of neonatal infections with significant morbidity and mortality, especially in extremely low and very low birth weight infants. We report a 24-days-old boy who presented with onychomycosis on left ring finger nail associated with fungal uri...
متن کاملDraft Genome Sequence of the Cellulolytic Fungus Chaetomium globosum
Chaetomium globosum is a filamentous fungus typically isolated from cellulosic substrates. This species also causes superficial infections of humans and, more rarely, can cause cerebral infections. Here, we report the genome sequence of C. globosum isolate CBS 148.51, which will facilitate the study and comparative analysis of this fungus.
