To identify the source of bleeding, Video-bronchoscope was performed, which revealed tracheomalacia and active bleeding in the left main bronchus, which was controlled by APC (figure 4). Bronchoalveolar lavage (BAL) was sent for cytology, anaerobic culture, Ziehl-Neelsen stain, and GeneXpert to detect Mycobacterium TB, all of which were unremarkable.
