Case report. Localized pulmonary zygomycosis without pre-existing immunocompromised status
Mycoses
|February 19, 2000
Summary
Pulmonary zygomycosis is rare in immunocompetent individuals. This case highlights pulmonary zygomycosis in an immunocompetent 72-year-old male, confirmed by histology and specific antibody staining.
Area of Science:
- Mycology
- Pulmonary Medicine
- Pathology
Background:
- Pulmonary zygomycosis is a rare fungal infection, typically associated with immunocompromised states.
- Early diagnosis and treatment are crucial for managing invasive fungal infections.
Observation:
- A 72-year-old male presented with a nodular shadow in the right lower lung on chest X-ray.
- Surgical resection (right lower lobectomy) was performed for the identified lung lesion.
Findings:
- Histological examination confirmed pulmonary zygomycosis.
- Fungal hyphae were identified using Grocott-Gomori methenamine silver staining.
- Specific identification of Rhizopus oryzae was achieved using a polyclonal antibody.
Implications:
- This case suggests pulmonary zygomycosis can occur in immunocompetent individuals.
- Accurate etiological diagnosis is vital for targeted antifungal therapy.
- Further research may elucidate risk factors for zygomycosis in immunocompetent hosts.
