CASE PRESENTATION: A 38-year-old male presented with cough, hemoptysis, generalized weakness and dyspnea on minimal exertion. Five months previously he was diagnosed with combined small and large cell lung carcinoma (T2bN3M0, Stage IIIb) and treated with Chemoradiation. Vital signs were normal and he had coarse rhonchi over both lung bases. Laboratory evaluation showed anemia (hemoglobin, 110 g/L) and leukocytosis (WBC count, 13,800 k/µL). Chest CT scan showed erosion of the anterior wall of the left mainstem bronchus. On Bronchoscopy, it was covered with thick necrotic, purulent pseudomembrane (figure-1), densely adherent to the underlying bronchial wall. On microscopic examination of the BAL specimen, fungal hyphae morphologically consistent with Aspergillus species were seen (figure-2). The patient was started on Voriconazole and scheduled for insertion of bronchial stents but he developed massive hemoptysis later that evening and died.
