Multiple myeloma is a malignant tumor, i.e., a monoclonal proliferation of plasma cells secreting gamma globulin. Gamma globulin is typically monoclonal and frequently associated with a passage of light-chain gamma globulin in urine (Bence-Jones protein). Light-chain gamma globulin may also deposit in extracellular spaces, most often in the kidneys, and aggregate into amyloid fibrils.
