Plasmablastic lymphoma (PBL) is a rare and highly invasive type of non-Hodgkin’s lymphoma. It is usually associated with immunosuppression and human immunodeficiency virus infection. PBL most commonly occurs in the oral cavity, lymph nodes, and in other extranodal sites. However, it rarely originates from bilateral sinuses. Herein, we report the case of a 59-year-old man diagnosed with primary PBL of the sinuses confirmed by endoscopic biopsy, imaging materials, histopathological examination, and immunohistochemistry. The patient underwent 4 cycles of chemotherapy and 22 rounds of radiation therapy for 8 months. Re-examination by sinus computed tomography revealed no obvious tumor tissue in the nasal cavity and sinuses, suggesting that treatment was effective. No local recurrence or distant metastasis was detected at 6-month follow-up after the end of treatment.
