FIRST PARAGRAPH: Amyloidosis is a benign accumulation of extracellular, insoluble, fibrillar protein. In general, the deposition of amyloid may be either localized or systemic and either primary or secondary. Laryngeal amyloidosis is rare, accounting for less than 1% of all benign laryngeal tumors. When it does occur, it is commonly localized and primary. Multifocal disease is present in up to 15% of patients. The disease typically manifests as hoarseness or vocal changes in the fifth to sixth decades, and it affects men and women equally.
