Cutaneous alternariosis in a kidney transplantation recipient: report of a case

Area of Science:

• Mycology
• Dermatology
• Infectious Diseases

Background:

• Phaeohyphomycoses are infections caused by darkly pigmented fungi.
• Dematiaceous fungi, particularly Alternaria species, are the primary agents.
• Risk factors include immunosuppression, local wounds, and systemic diseases.

Observation:

• A rare case of cutaneous phaeohyphomycosis caused by Alternaria alternata is presented.
• The patient was immunocompromised, presenting with unusual clinical aspects.
• The infection showed a favorable response to therapeutic intervention.

Findings:

• Alternaria alternata is identified as the causative agent of phaeohyphomycosis.
• The clinical presentation of cutaneous alternariosis was rare and noteworthy.
• Successful treatment was achieved, indicating therapeutic efficacy.

Implications:

• Highlights Alternaria species as potential opportunistic pathogens.
• Stresses the importance of considering fungal infections in immunocompromised patients.
• Aids in the differential diagnosis of granulomatous or ulcerative dermatological lesions.
