case_images: a Computed tomography (CT) revealed enlargement of the right lobe of the thyroid gland causing severe compression and stenosis of the trachea. b A metallic stent was placed in the trachea. The size of the thyroid gland is normalized after drug therapy for malignant lymphoma. c CT revealed severe stenosis of the metallic stent 8 years after treatment.

case_images: Severe tracheal stenosis due to abnormal thyroid swelling was observed (Fig. 1a). The disease was treated by systemic chemotherapy, and complete remission was achieved (Fig. 1b). Intraluminal granulation formation and stenosis were observed (Fig. 1c, 2).
case_images: A 3-D reconstructed image of the stenotic trachea caused by granulation in the metallic stent.

case_images: Intraluminal granulation formation and stenosis were observed (Fig. 1c, 2).
case_images: Macroscopic and microscopic (HE staining) of the extracted metallic stent. Extreme granulation is observed in the lumen.
