Nasal rhinosporidiosis with an atypical presentation

Area of Science:

• Mycology
• Infectious Diseases
• Otorhinolaryngology

Background:

• Rhinosporidiosis is an endemic fungal infection in specific regions of India and Sri Lanka.
• Caused by Rhinosporidium seebri, transmission occurs through contaminated water, often from cattle feces.
• The disease characteristically manifests as multiple, granulomatous, and bleeding polyps.

Observation:

• This report details an atypical case of rhinosporidiosis.
• The infection presented as a solitary polyp.
• The lesion was located in an uncommon anatomical site, delaying diagnostic suspicion.

Findings:

• A unique, single-site presentation of Rhinosporidium seebri infection was documented.
• The uncommon location of the polyp made rhinosporidiosis an unlikely initial consideration.
• Diagnostic challenges were encountered due to the atypical clinical manifestation.

Implications:

• This case expands the understanding of rhinosporidiosis clinical variability.
• Highlights the importance of considering rare presentations in endemic areas.
• May influence diagnostic algorithms for unusual localized lesions in regions where rhinosporidiosis is endemic.
