Primary Localized Laryngeal Amyloidosis: Report of 3 Cases With Long-term Follow-up and Review of the Literature

Abstract

The demonstration of monoclonal light chain expression in the plasmacytic infiltrate and amyloid component in the absence of systemic lymphomas indicates that localized laryngeal amyloidosis may represent a form of benign monoclonal plasma cell dyscrasia. A close follow-up of the patients may be indicated for early detection of recurrences.
