Nonsecretory Multiple Myeloma Presenting as Recurrent Vertebral Compression Fractures in an Older Male Patient

초록

Nonsecretory multiple myeloma is a rare variant of multiple myeloma characterized by the proliferation of clonal plasma cells in the bone marrow. It is difficult to establish an early and accurate diagnosis of nonsecretory multiple myeloma because in nonsecretory myeloma cases, monoclonal immunoglobulin cannot be detected in the serum or urine via electrophoresis. In this report, we describe a case of nonsecretory multiple myeloma presenting as recurrent vertebral compression fractures in a 70-year-old male patient and suggest that nonsecretory multiple myeloma can be included in the differential diagnosis of multiple and recurrent vertebral compression fractures, despite the lack of detectable monoclonal immunoglobulin in the serum or urine by electrophoresis.
