{Abstract}: Extramedullary plasmacytoma (EMP) is an uncommon tumor marked by the monoclonal growth of plasma cells without the characteristics of multiple myeloma. EMP represents 3% of all plasma cell tumors. An 89-year-old male patient with hypertension was admitted to our tertiary care hospital with uncontrolled unilateral epistaxis. After a year and a half of recurring epistaxis, the patient's bleeding became more frequent and could no longer be controlled with nasal packing. Angiofibroma was suspected as the initial differential diagnosis, and angiofibroma embolization was performed. The patient experienced difficulty swallowing and slurred speech and was diagnosed with an ischemic stroke. However, antiplatelet and tranexamic acid medications were contraindicated due to bleeding risks. The patient underwent functional endoscopic sinus surgery, and unexpectedly, histology results revealed a plasmacytoma. After surgery, the patient remained stable and was discharged for further management.
