Arthrocladium fulminans Arthritis and Osteomyelitis

Area of Science:

• Medical Mycology
• Infectious Diseases
• Clinical Case Reports

Background:

• Arthrocladium fulminans is a rare fungal species, with only one prior reported human infection.
• The only previously documented case involved a patient with GATA-2 immunodeficiency.

Observation:

• This report details the second human case of Arthrocladium fulminans infection.
• It is the first reported instance of septic arthritis and osteomyelitis caused by this fungus.
• The patient was immunocompetent and resided in Mayotte, a French island in the western Indian Ocean.

Findings:

• The patient presented with septic arthritis and osteomyelitis.
• Successful treatment was achieved through surgical debridement and a 6-month course of antifungal medication.
• The case was in an immunocompetent individual, contrasting with the previous report.

Implications:

• This second observation strengthens the evidence for the pathogenicity of Arthrocladium fulminans in humans.
• It expands the known clinical spectrum of infections caused by this rare fungal species.
• Highlights the potential for invasive disease even in immunocompetent hosts.
