Area of Science:

  • Mycology
  • Infectious Diseases
  • Immunology

Background:

  • Fungal sinusitis is a significant concern in immunocompromised individuals.
  • Aspergillus species are the most common fungal pathogens implicated.

Observation:

  • A case of fungal sinusitis caused by Pseudallescheria boydii (P. boydii) is presented.
  • The patient experienced recurrent sinusitis over two years, coinciding with episodes of neutropenia.

Findings:

  • Despite comprehensive surgical and antifungal treatment, the P. boydii sinusitis persisted.
  • Neutropenia was a critical factor in the recurrence of infection.

Implications:

  • This case underscores the importance of adequate neutrophil counts in managing fungal sinusitis in immunocompromised patients.
