Parathyridaria percutanea and Subcutaneous Phaeohyphomycosis

Area of Science:

• Mycology
• Infectious Diseases
• Transplant Medicine

Background:

• Subcutaneous phaeohyphomycosis is a fungal infection affecting the skin and underlying tissues.
• Renal transplant recipients are immunocompromised, increasing their susceptibility to opportunistic infections.
• Emerging fungal pathogens pose a significant threat to immunocompromised individuals.

Observation:

• Parathyridaria percutanea was identified as the causative agent in a renal transplant recipient with subcutaneous phaeohyphomycosis.
• The same fungus was subsequently identified in four additional patients with similar clinical presentations.
• A review of existing literature revealed five previously reported cases of P. percutanea infections.

Findings:

• This study reports a total of nine cases (five new, five literature) of P. percutanea-associated subcutaneous phaeohyphomycosis.
• The findings highlight P. percutanea as a significant emerging pathogen in renal transplant recipients in India.
• The clinical and mycological characteristics of P. percutanea infections are further elucidated.

Implications:

• Early identification and diagnosis of P. percutanea are crucial for effective management of subcutaneous phaeohyphomycosis.
• Increased awareness among clinicians treating transplant recipients about this emerging fungus is warranted.
• Further research into the epidemiology, pathogenesis, and treatment of P. percutanea infections is necessary.
