A Case of Multiple Extramedullary Plasmacytoma Arising from Both Nasal Cavity and Nasopharynx / 대한이비인후과학회지

ABSTRACT

Extramedullary plasmacytoma is a neoplastic proliferation of plasmacytes in reticuloendothelial tissue and is found predominantly in the head and neck region, especially in the upper respiratory tract and the oral cavity. The most common subsites are the paranasal sinuses, nasal cavity and nasopharynx. The tumor can be staged according to the spread of the disease and has been rarely met in the form of multiple lesions below the 10%. We have recently experienced a case of multiple extramedullary plasmacytoma arising from both nasal cavity and nasopharynx treated with surgical excision and postoperative radiotherapy.
