A case of extramedullary plasmacytoma originating in the left submaxillary lymph node in a 63-year-old man was reported. The diagnosis of plasmacytoma was made on the basis of a monoclonal proliferation of IgG, K type of plasma cells by means of immune antibody staining. About 70% of extramedullary plasmacytoma cases have been reported to have a primary lesion in the upper respiratory tract and the oral cavity with cervical lymph node metastases in 8-30%. The present case was considered to be of submaxillary lymph node origin in view of failure of various examinations to detect lesions in the oral cavity and the upper part of the respiratory tract.
报告了一例起源于一名63岁男性左下颌下淋巴结的髓外浆细胞瘤。通过免疫抗体染色，依据IgG单克隆增殖、K型浆细胞确诊为浆细胞瘤。据报道，约70%的髓外浆细胞瘤病例原发灶在上呼吸道和口腔，8%-30%伴有颈部淋巴结转移。鉴于各项检查均未在口腔和呼吸道上部发现病变，本病例被认为起源于下颌下淋巴结。
