Multiple myeloma is a malignant neoplasm of plasma cells that usually invades the bone marrow replacing normal bone marrow and producing large amounts of light chains of immunoglobulins (Ig) [1]. Clinical manifestations are related to the accumulation of these proteins in vital organs such as kidney and heart.
