We present the case of a 50-year-old Hispanic man who presented to the emergency department with an acute right femur fracture after 3 months of intermittent discomfort in the right leg. He was eventually diagnosed with immunoglobulin D (IgD) multiple myeloma, a rare class of myeloma that is often of advanced stage at diagnosis. Fortunately, our patient was stage I at diagnosis and did not have hypercalcemia, anemia, or renal insufficiency, as is common with myeloma. This report describes a rare case of an uncommon condition and highlights the fortunate aspects of this patient's unfortunate diagnosis.
