Multiple Myeloma in a Young Adult

Abstract

Case: We present a 27-year-old man who presented with worsened back pain after a fall from a ladder. Unrelenting pain prompted the discovery through imaging and biopsy of a large pelvic plasmacytoma along with innumerable axial and appendicular lytic osseous lesions. The patient was soon thereafter diagnosed with light chain multiple myeloma (MM) and underwent measurable residual disease response-adapted consolidation treatment. Conclusion: The typical age at diagnosis for MM is 60 to 70 years. This case emphasizes the need to consider MM when diagnosing patients younger than 30 years, especially those with numerous bony lesions.
