Abstract:
A previously well 59-year-old man developed necrotizing, invasive cellulitis and subsequent osteomyelitis at what was judged to be the site of a bite or sting. The pathogen isolated was Apophysomyces elegans. Eventually, in addition to treatment with intravenous amphotericin B, en bloc resection was required for cure. Only six previous cases of A. elegans infection have been reported in the literature. The lack of underlying disease in six of the total of seven cases contrasts with the usual findings for other zygomycoses. This article describes all seven reported cases as well as the characteristics of this unique fungal pathogen.
Insights
A rare fungal infection caused by Apophysomyces elegans led to severe cellulitis and bone infection in a healthy man. Treatment involved antifungal medication and surgical removal of infected tissue.
Area of Science:
- Mycology
- Infectious Diseases
- Dermatology
Background:
- Zygomycoses are a group of fungal infections, often associated with underlying health conditions.
- Apophysomyces elegans is a rare fungal genus known to cause infections.
Observation:
- A previously healthy 59-year-old man presented with necrotizing cellulitis and osteomyelitis.
- The infection occurred at the site of a suspected insect bite or sting.
- Apophysomyces elegans was identified as the causative pathogen.
Findings:
- This case represents the seventh reported infection caused by Apiphenylomyces elegans.
- Six out of seven reported cases occurred in individuals without significant underlying diseases.
- Treatment required intravenous amphotericin B and en bloc resection for successful cure.
Implications:
- Apiphenylomyces elegans infections can occur in immunocompetent individuals, unlike many other zygomycoses.
- Early diagnosis and aggressive treatment, including surgical intervention, are crucial for managing these infections.
- Further research into the pathogenesis and epidemiology of Apiphenylomyces elegans is warranted.
