Isolated laryngeal plasmacytosis.

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.
