Cryptococcus neoformans can infect vocal cords, presenting similar to other infiltrative diseases. Diagnosis requires tissue biopsy, and treatment with fluconazole for at least six weeks is recommended.
Area of Science:
- Mycology
- Otolaryngology
- Infectious Diseases
Background:
- Cryptococcus neoformans is an opportunistic fungal pathogen.
- Vocal cord infections are rare but possible.
- Inhaled corticosteroids are a known risk factor for opportunistic infections.
Purpose of the Study:
- To describe the clinical presentation and diagnostic challenges of Cryptococcus neoformans infection of the vocal cords.
- To determine the efficacy of antifungal treatment for this condition.
Main Methods:
- Case report and literature review.
- Diagnostic procedures included endoscopy and tissue biopsy.
- Treatment involved oral fluconazole.
Main Results:
- Endoscopic findings were non-specific, mimicking other infiltrative lesions.
- Tissue biopsy confirmed Cryptococcus neoformans infection.
- A minimum treatment course of fluconazole 400 mg daily for 6 weeks was effective.
Conclusions:
- Vocal cord cryptococcosis should be considered in patients with risk factors, especially those using inhaled corticosteroids.
- Tissue biopsy is crucial for accurate diagnosis.
- Aggressive antifungal therapy is necessary for a successful outcome.
