A case of a solitary extramedullary plasmacytoma of the nasal cavity is reported. A man, aged 35, complained of epistaxis and nasal discharge for three months. Bence-Jones protein in the urine was absent. There was no evidence of bone involvement on repeated x-ray examinations. Preoperatively, telecobalt irradiation was performed. The tumor was completely removed by an approach employing a combined route through the maxillary sinus and endonasally. Histologically, the tumor proved to be a plasmacytoma. A year after the operation the patient has no recurrence or any evidence of generalized manifestation.
Forty-five cases of plasmacytomas of the head and neck in the Japanese literature are reviewed.
