Endobronchial mucormycosis diagnosed by fiberoptic bronchoscopy

Introduction: Endobronchial mucormycosis is very rare with only few cases reported in the literature. Here, we report a rare presentation of pulmonary mucormycosis in a diabetic patient who presented with left lung collapse. Bronchoscopy revealed an endobronchial growth, mimicking a tumor, causing complete occlusion of the left main bronchus. Histopathology confirmed the diagnosis of invasive mucormycosis. Case presentation: Male patient 35 years old with accidental discovered Diabetes Mellitus, complained of hoarseness of voice and dry irritating cough that didn't respond to antitussives and nonspecific treatment. CT chest was done and revealed left total lung collapse. Fiberoptic bronchoscopy was done and revealed total occlusion of the left main bronchus with whitish fungating glistening tissue from which biopsies were obtained. Histopathological examination was consistent with mucormycosis. A trial of medical treatment failed after which the patient was referred for surgical resection. Conclusion: Successful treatment of mucormycosis requires early diagnosis; prompt administration of antifungal therapy, and surgical intervention when applicable. Aggressive surgical intervention to remove necrotic tissue is generally accepted as the therapeutic mainstay for endobronchial obstructing mucormycosis
