Pyrenochaeta romeroi causing subcutaneous phaeohyphomycotic cyst in a diabetic female

Area of Science:

• Mycology
• Infectious Diseases
• Dermatology

Background:

• Opportunistic subcutaneous fungal infections are increasing globally.
• Immunosuppression from conditions like diabetes, AIDS, and cancer therapy contributes to this rise.
• Dematiaceae fungi, such as Pyrenochaeta romeroi, are soil saprophytes with pathogenic potential.

Purpose of the Study:

• To report a rare case of subcutaneous phaeohyphomycotic cyst.
• To identify the causative agent, Pyrenochaeta romeroi.
• To highlight the association with diabetes mellitus.

Main Methods:

• Case presentation of a patient with a subcutaneous cyst.
• Identification of the fungal pathogen through mycological examination.
• Review of relevant literature on Pyrenochaeta romeroi infections.

Main Results:

• A subcutaneous phaeohyphomycotic cyst was diagnosed.
• The causative agent was identified as Pyrenochaeta romeroi.
• The patient had a history of diabetes mellitus, a known risk factor for opportunistic infections.

Conclusions:

• Pyrenochaeta romeroi can cause rare subcutaneous infections.
• Diabetic patients are at increased risk for opportunistic fungal infections.
• Subcutaneous phaeohyphomycosis requires accurate diagnosis and management.
