Laryngeal amyloidosis is an uncommon disorder that consist of subepithelial deposits of amyloid. It may occur as isolated localized deposits or as a part of generalized systemic amyloidosis. Localized amyloidosis is a benign disease as opposed to systemic amyloidosis. Its management are medical treatment and surgical intervention. Medical treatment including corticosteroids and radiotherapy are ineffective. Surgical intervention include localized endoscopic excision (via either cold knife or CO₂ laser) or open operation. And it is important to use technique that will minimize trauma to the larynx. The purpose of this presentation is to report the case of localized laryngeal amyloidosis only treated with localized endoscopic excision (with cold knife) with good post operative state and no evidence of recurrence until now.
