Fig 1 Imaging of the tracheal lesion. Preoperative 3-dimensional reconstructed bronchoscopic view of the lesion from (A) high in the trachea and (B) just above the lesion around the level of the carina. (C) A coronal computed tomography image reveals partially obstructive lesion just superior to the carina.

Fig 3 (A) Low-magnification hematoxylin and eosin stain of tracheal lesion demonstrates dense cellular infiltrate with an irregular whorled pattern of fibrosis that is characteristic of immunoglobulin G4-related disease (original magnification ×10). (B) High magnification of panel A shows dense collagen and storiform fibrosis (original magnification ×20).
