Most common primary malignant bone tumor in adults (median age ~65 yrs). Neoplastic proliferation of plasma cells → monoclonal immunoglobulin production. Classical CRAB features: hyperCalcemia, Renal failure, Anemia, Bone lesions. Radiology: multiple punched-out lytic lesions, diffuse osteopenia. Diagnosis: SPEP/UPEP (M protein, Bence-Jones), bone marrow biopsy (>10% plasma cells). Ortho role: prophylactic fixation of impending fractures (Mirel’s >8), spinal decompression, bisphosphonates, vertebroplasty/kyphoplasty. Systemic therapy: chemo, immunomodulators, stem cell transplant.
