Reports of amyloidosis on larynx and trachea is rare, however it is increasing in number recently in japan and other countries. Genesis and etiology of this disease is still not well known. Our case was a 57 year-old male, with chronic granaloma occurring between subglottic and cricoid space in the air way with amyloid degeneration which interfered with the respiration and phona-tion. In this case examined histopathological, viral infection was thought to be one of the important cause. Therapies by steroid hormone, large dosis of vitamin E and antibiotics were of little effect. Surgical procedure was finally taken. The grans. loma was shaved off under laryngofissure. Ample air way was built and skin grafted immediately. Opening of laryngofissure was closed after epitheli. sation had completed in the air way.
