Abstract
Malignant lymphoma is a malignant tumor that occurs in the lymphocytes but can also occuranywhere in the body. On the other hand, malignant lymphomas originating from the naso-pharyngeal space are very rare. We experienced a case of 84-year-old female patient with ahuge nasopharyngeal mass, who had no complaints other than right nasal congestion, inter-mittent rhinorrhea, and sneezing. A physical examination revealed a large, polypoid, transpar-ent mass at her right nasal cavity. Nasal polyp was suspected and endoscopic sinus surgerywas performed. On histological examination, she was diagnosed with diffuse large B celllymphoma, with CD20, BCL-2, and BCL-6 positive. Low dose maintenance chemotherapywas carried out in consideration of the patient¡¯s age. A complete remission is expected basedon the imaging tests following chemotherapy. We report a huge malignant lymphoma that oc-curred in an elderly patient¡¯s nasopharyngeal space and successful low dose chemotherapywith a review of literature.
