Plasmacytoma is the disease with proliferation of neoplastic plasma cells, and that localized in the oral region is relatively rare. We have described a case of plasmacytoma which originated in the mandible. A 67-year-old woman was referred to us on May 8, 1989, with a chief complaint of swelling of the lower right molar region. From the present illness and the X-ray findings, clinical diagnosis was suspected the ameloblastoma. The general physical examination revealed WBC 3.89×10^3/ul, Fib 459mg/dl, Fe 43μg/dl, APTT 44.9s (58%). Resection and reconstruction of the mandible were performed under general anesthesia. We investigated an excised tissue by histological and immunohistochemical method. Moreover, serum and urine immunoelectrophoresis were performed. Consequently, this case was diagnosed as plasmacytoma with IgG and λchain, and Bence-Jones protein was negative.
