case_images: He was evaluated with contrast-enhanced computed tomography (CECT) chest, which showed a mass along the posterior wall of the trachea just above the carina involving the right lateral and posterior walls, measuring 19 mm x 19 mm x 15 mm with significant tracheal luminal narrowing and a large extraluminal component [Figure 1a and b].

case_images: A well-encapsulated tracheal mass measuring 2 cm x 2 cm was seen just above the carina on the posterior wall of the trachea [Figure 2a]. Tension-free, end-to-end tracheal anastomosis was done using 4-0 Polydioxanone (PDS) interrupted sutures [Figure 2b].

case_images: The biopsy report of the tumor showed benign schwannoma with submucosal layer showing spindle cell tumor [Figure 3a] and diffuse S100 positivity on immunohistochemistry (IHC) [Figure 3b].
