A Case of Extramedullary Plasmacytoma Presenting with the Mass in Nasal Cavity

ABSTRACT

Extramedullary plasmacytoma (EMP) arises outside the bone marrow, particularly in the head and neck region (nasopharynx, nasal cavity, sinuses, and tonsils etc), and can be associated with multiple myeloma (MM). The most frequently involved sites of EMP are head and neck regions, although it accounts for less than 1% of all head and neck malignancy. It is essential for otolaryngologists and head and neck surgeons to be familiar with this entity because total excision and radiation therapy for plasmacytomas can be curative in patients who have no underlying overt plasma cell dyscrasias. We have recently experienced a case of solitary EMP arising from left nasal cavity and report it with a review of literature.
