摘要:

A rare case of extramedullary plasmacytoma in the sino-nasal cavity is presented. During a prolonged clinical course, the tumor has recurred several times after irradiation, chemotherapy and surgery, and presented in the clavicular bone as well. Immunohistochemical staining of each tumor showed IgA k phenotype, and immunoelectrophoresis of the serum showed overproduction of IgA with k light chains. Although an elevation of serum IgA persists, the patient has remained well without evidence of overt multiple myeloma.
