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.
