Pulmonary mucormycosis masquerading as endobronchial tumour in an immunocompetent pregnant young lady

Pulmonary mucormycosis is a rare but rapidly progressing and life-threatening fungal infection, usually affecting immunocompromised patients. We report a case of a previously healthy young lady who presented with prolonged cough, weight loss, and haemoptysis. Imaging showed left hilar mass with infiltration into the left main bronchus and concurrent mediastinal lymphadenopathy. Flexible bronchoscopy revealed an endobronchial mass occluding the left main bronchus. Tumour debulking was performed using rigid bronchoscopy with cryoprobe and snares. Histopathological examination revealed inflamed tissue with fungal organism. Fungal polymerase chain reaction (PCR) confirmed Rhizopus microsporus. She was treated with two weeks of intravenous amphotericin-B with complete clinical and radiological resolution.
