On February 28, 2018, bronchoscopic examination revealed that the lumen was blocked by a lump 3cm below the glottis, resulting in 95% of the lumen stenosis and a large amount of secretions on the surface.

Under the bronchoscope, a lump 3 cm below the glottis could be seen obstructing the airway and causing 95% of the airway stenosis, with a large amount of white viscous secretion on the surface (Fig. 1).The abnormal secretions were sucked out by a bronchoscope, then the needle-shaped electric knife was introduced through the forceps of the bronchoscope to cut the left tracheal lump repeatedly, then the cryosurgery probe was introduced to freeze the cut site, and the argon knife was used to stop the bleeding.
On February 28, 2018, bronchoscopic examination revealed that the tumors invaded the tracheal carina and left and right main bronchi.

When the airway stenosis decreased to 40% after treatment, bronchoscopy was continued to access the left and right main bronchi; the lump was found to invade the tracheal carina and the left and right main bronchi (Fig. 2).
(A) Biopsy of bronchial lesion showed amyloidosis (Congo red, x100).(B) Biopsy of bronchial lesion showed amyloidosis (Congo red, x400). (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)

Postoperatively, patients' vital signs were stable, dyspnea was relieved, and a small amount of hemoptysis that was found at the beginning, disappeared in 2 days, and the pathological return was amyloidosis (Fig. 3A and B).The patient was discharged on March 5, 2018.
(A) On March 27, 2018, before the second bronchoscopy treatment, bronchoscopic examination revealed that there was approximately 40% widespread stenosis from 3 cm below glottis till tracheal carina.(B) On March 27, 2018, after the second bronchoscopy treatment, bronchoscopic examination revealed that there was approximately 20% widespread stenosis from 3 cm below glottis till tracheal carina.

Bronchoscopic examination showed that there was approximately 40% widespread stenosis from 3 cm below glottis till the tracheal carina (Fig. 4A). Thereafter, biopsy forceps were used to reduce the tracheal stenosis to 20% (Fig. 4B), and bronchoscopy was continued to the left and right main bronchi.

The patient underwent two follow-up bronchoscopy examinations on July 3, 2018 and January 30, 2019 (Fig. 5, Fig. 6, respectively), with no recurrence of the disease.
