AbstractAmyloidosis is a group of idiopathic clinical syndromes caused by the deposition of insoluble fibrillar proteins (amyloid) in the extracellular matrix of organs and tissues. These deposits disrupt the function of the target organ. Amyloidosis can manifest as a systemic disease or a single-organ involvement (local form). Its etiology still remains unclear. Deposits of amyloid in the larynx are rare, accounting for between 0.2 and 1.2% of benign tumors of the larynx. In this retrospective study, we report the clinical aspects, diagnosis, treatment and follow-up of five female patients with localized laryngeal amyloidosis without systemic involvement. The patients were all treated successfully using microlaryngoscopy with CO2 laser or cold instruments. Prognosis is excellent; however, appropriate follow-up is an important part of the long-term management of this disease in order to prevent and control the possibility of local recurrence.
