Primary cutaneous Aspergillus ustus infection: second reported case

Area of Science:

• Mycology
• Infectious Diseases
• Dermatology

Background:

• Primary cutaneous fungal infections are uncommon in clinical practice.
• Aspergillus species are opportunistic pathogens, rarely causing primary skin disease.

Observation:

• A case of primary cutaneous Aspergillus ustus infection in an immunocompromised patient is presented.
• Diagnosis was confirmed through fungal culture and fluorescent antibody staining.

Findings:

• This represents the second documented case of primary cutaneous infection by Aspergillus ustus.
• The previous case involved an immunosuppressed patient with no apparent geographical or temporal link.

Implications:

• Highlights the potential for rare Aspergillus species to cause invasive cutaneous disease in immunocompromised hosts.
• Emphasizes the importance of considering unusual fungal pathogens in refractory or atypical skin infections.
• Contributes to the limited literature on Aspergillus ustus cutaneous infections, aiding future diagnosis and management.
