Introduction:
Laryngeal plasmacytosis (LP) is a rare benign lesion of mature polyclonal plasma cells, which should be differentiated from extramedullary plasmacytoma.
Case Report:
Isolated laryngeal plasmacytosis was discovered in a 59-year-old woman, free of symptoms other than chronic hoarseness.
Discussion:
Histological presentation, treatment modalities and prognosis are discussed.
Conclusion:
Laryngeal plasmacytosis is a rare benign lesion that must be considered in case of submucosal polyclonal plasma cell infiltrate.
