A pseudo tumoral sinusitis caused by Bipolaris sp

Area of Science:

• Mycology
• Infectious Diseases
• Otolaryngology

Background:

• Rhinosinusitis is a common condition with diverse etiologies.
• Fungal infections of the sinuses are increasingly recognized, particularly in allergic fungal sinusitis.
• Bipolaris species are known environmental fungi, often implicated in allergic conditions.

Observation:

• A case of rhinosinusitis caused by Bipolaris sp. in an immunocompetent patient is reported.
• This is the first documented case in France.
• The patient resided in a warm and damp climate in the south-east of France.

Findings:

• Bipolaris sp. was identified as the causative agent of rhinosinusitis.
• The patient's immune system was not compromised (immunocompetent).
• Bipolaris sp. is frequently isolated in cases of allergic fungal sinusitis.

Implications:

• Bipolaris species should be considered potential opportunistic human pathogens, especially in tropical and subtropical regions.
• Clinicians in warm, humid climates should consider Bipolaris sp. in the differential diagnosis of rhinosinusitis.
• Further research is warranted to understand the pathogenic potential of Bipolaris species in humans.
