Multiple myeloma (MM) is an incurable hematological malignancy of plasma cell origin. Plasma cell clonality and dysfunctional immunoglobulin production characterize the disease. The consequences of abnormal plasma cell growth are manifested by a myriad of symptoms and signs that often have significant impact on the patient's quality of life. These include pancytopenia secondary to predominant distribution of tumor cells within the bone marrow along with many other effects.
