Non-secretary multiple myeloma in a young Ethiopian: case report

Non secretary multiple myeloma (NSMM) is a rare variant of multiple myeloma (MM) with similar clinical and radiologic picture but without monoclonal gammopathy in the serum or urine. A non-secretary type multiple myeloma was diagnosed clinically and radiologically in a young Ethiopian presenting with low back pain. He had a diffuse osteopenia of the iliac bone, punched out lytic skull lesions and plasmacytosis on the bone marrow aspiration. But the serum electrophoresis of the patient did not show M component. Both the variant and the age of the patient are unique features observed in this case report.
