Figure 1. CASE 1: (A) Chest-enhanced computed tomography revealed thickening of the tracheal wall (A1) and the main bronchi (A2) (arrow). (B) Flexible bronchoscopy showed an imbricate, oedematous tracheal wall. (C) Bronchial biopsy specimens indicated bronchitis with moderate eosinophilic (white arrow) and mild plasmacytic (black arrow) infiltration. (haematoxylin and eosin stain)
Figure 2. CASE 2: (A) Chest plain computed tomography revealed thickening of the tracheal wall (A1) and the main bronchi (A2) (arrow). (B) Flexible bronchoscopy showed an oedematous tracheal wall. (C) Bronchial biopsy specimens indicated bronchitis with mild plasmacytic infiltration (arrow). (haematoxylin and eosin stain)
Figure 3. CASE 3: (A) Chest plain computed tomography revealed thickening of the tracheal wall (A1) and the main bronchi (A2) (arrow). (B) Flexible bronchoscopy showed an oedematous tracheal wall. (C) Bronchial biopsy specimens indicated a palisading granuloma. (haematoxylin and eosin stain)
