myeloma


myeloma
= multiple myeloma; = myelomatosis; n.
a malignant disease of the bone marrow, characterized by two or more of the following criteria:
1) the presence of an excess of abnormal malignant plasma cells in the bone marrow;
2) typical lytic deposits in the bones on X-ray, giving the appearance of holes;
3) the presence in the serum of an abnormal gammaglobulin, usually IgG (an immunoglobulin; see paraprotein). Bence-Jones protein may also be found in the serum or urine. The patient may complain of tiredness due to anaemia and of bone pain and may develop pathological fractures. Treatment is usually with such drugs as melphalan or cyclophosphamide, with local radiotherapy to particular areas of pain.
