Abstract
Multiple myeloma (MM) is a progressive and fatal desaese arising by neoplastic proliferation of plasma cells in the clinic mainly common skeletal lesions, anemia, against extremist tendencies, hypercalcemi, renal function impairment. In the presence of overt clinical signs (eg, sedimentation rate, hypercalcemia, anemia, lytic bone lesions, such as hypergammaglobulinemia) although it can be placed easily recognize further investigations are required in atypical cases. As with the light chain myeloma cases which could not be detected in serum protein electrophoresis is readily determined by immunofixation electrophoresis. In our case, a rare kappa light chain myeloma and immunofixation electrophoresis has been referred to the importance of the diagnosis
