A Case of Extramedullary Plasmacytoma of the Hypopharynx / 대한이비인후과학회지

ABSTRACT

Plasmacytoma is a rare malignancy characterized by a monoclonal proliferation of plasma cells, and is generally classified into a solitary plasmacytoma of bone and extramedullary plasmacytoma. Extramedullary plasmacytoma of the head and neck usually involves submucosal tissues in the nasopharynx and paranasal sinuses. The hypopharyneal involvement of the tumor, however, is very uncommon. We report a case of hypopharyngeal plasmacytoma treated by chemoradiation therapy with a review of literature.
