Abstract

Immunoglobulin D-secreting Multiple Myeloma (IgD MM) is a rare form of the disease, accounting for 1% to 2% of cases. Patients present frequently at a younger age and with more advanced disease than in the more common myeloma isotypes, contributing to shorter Overall Survival (OS) and Progression Free Survival (PFS). Autologous Stem Cell Transplant (ASCT) and greater access to novel agents are key to reducing this gap. As with other myeloma isotypes, there is a small group of long-term survivors. Interphase Fluorescence in situ Hybridization (iFISH) detects abnormalities in the majority of cases. 1q21 amplification, associated with late myeloma, and t(11;14), are more common than in other myeloma isotypes. No clear difference in del(17p) frequency has been shown. We present a case report of an IgD MM patient in our care which, whilst not entirely typical of the genre, illustrates the diagnostic and management challenges when caring for these patients.
