ABSTRACT
The article presents outcomes of scratch test performed for a 47 year old patient suffering from plasma cell myeloma. He was noted to have 9660 mg/dL of monoclonal immunoglobulin G in her serum. T high concentration of paraprotein also resulted in a noticeably homogeneous basophilic stained background of her peripheral blood smear, readily demonstrated after making a scratch on the slide and comparing the abnormally stained proteinaceous material to the clean colorless back ground of the slide. This phenomenon is not pathognomonic of plasma cell myeloma but indicates a hypergammaglobulinemia that may be due to either a paraprotein or reactive increase in immunoglobulins.
