Abstract: | Paraproteinemia is characterised by clonal proliferation of plasma cells. A common laboratory finding in paraproteinemia being a monoclonal peak in serum protein electrophoresis (M band). But there are factors which produce a peak similar to M spike in serum protein electrophoresis and these factors are known as pseudoparaproteins. This case report discusses a rare cause of pseudo M spike in a known case of autoimmune hemolytic anaemia due to administration of drug-Rituximab, a monoclonal antibody by itself. |
