title: [A solitary extramedullary plasmacytoma of the nasopharynx].
abstract: A 72-year-old male, complaining of epistaxis, was referred to our hospital where a physical exam revealed a tumorous mass in the nasopharynx. A subsequent immunohistopathological investigation found that the tumor mass was a plasmacytoma with IgG and a lambda chain. Electrophoresis of a serum sample revealed a normal value and there was no signs indicating a multiple myeloma on x-ray surveys of the skeleton, or from bone marrow aspiration or scintigraphy. Thus the diagnosis was an extramedullary plasmacytoma and the patient received a combined treatment of chemotherapy, radiotherapy, and surgery. Since surgery, the patient has had neither a recurrence or a metastasis of the tumor for four years and three months.
