Pulmonary mucormycosis: the last 30 years

Area of Science:

• Mycology
• Infectious Diseases
• Pulmonology

Background:

• Pulmonary mucormycosis is an uncommon opportunistic fungal infection.
• Literature on this condition is sparse, necessitating further clinical characterization.

Observation:

• A review of 87 cases identified key risk factors including diabetes mellitus, hematologic cancers, renal insufficiency, and organ transplantation.
• Pulmonary involvement often predilected upper lobes, and the air crescent sign on chest X-rays indicated a higher risk of pulmonary hemorrhage.
• Diagnosis was aided by fiberoptic bronchoscopy, with histopathology proving more sensitive than fungal cultures.

Findings:

• The overall survival rate for pulmonary mucormycosis was 44%.
• A combined medical-surgical approach was associated with better patient outcomes compared to medical management alone.

Implications:

• This rare but often fatal disease should be suspected in immunocompromised patients unresponsive to antibacterial therapy.
• Early recognition and aggressive management, including systemic antifungal therapy, surgical resection, and control of underlying conditions, are crucial for improving cure rates.
