| myeloid metaplasia | A progressive disease of the bone marrow where neoplastic bone marrow stem cells lodge and grow in multiple sites outside the bone marrow. Typically, there is enlargement of the spleen and a gradual replacement of the bone marrow elements by fibrosis (scarring), progressive anaemia and variable changes in the number of white blood cells and platelets. Diagnosis is by bone marrow biopsy. There is no definitive treatment for this disorder that has been shown to affect life span favorably. Origin: Gr. Plassein = to form (27 Sep 1997) |

| myeloid sarcoma | <tumour> A malignant tumour of immature myeloid cells, frequently subperiosteal, associated with or preceding granulocytic leukaemia. See: chloroma. Synonym: myeloid sarcoma. (05 Mar 2000) |
| myeloid series | The granulocytic and the erythrocytic series. (05 Mar 2000) |
| myeloid tissue | Bone marrow consisting of the developmental and adult stages of erythrocytes, granulocytes, and megakaryocytes in a stroma of reticular cells and fibres, with sinusoidal vascular channels. (05 Mar 2000) |
| myeloidin | <physiology> A substance, present in the protoplasm of the retinal epithelium cells, and resembling, if not identical with, the substance (myelin) forming the medullary sheaths of nerve fibres. Origin: Myelin + -in. Source: Websters Dictionary (01 Mar 1998) |
| myeloidosis | General hyperplasia of myeloid tissue. (05 Mar 2000) |
| myeloleukaemia | A form of leukaemia in which the abnormal cells are derived from myelopoietic tissue. (05 Mar 2000) |
| myelolipoma | <oncology, tumour> A rare benign tumour of the adrenal gland. (09 Oct 1997) |
| myelolymphocyte | Rarely used term for an abnormal form of the lymphocytic series in the bone marrow, and presumed to be formed in that tissue. (05 Mar 2000) |
| myelolysis | Decomposition of myelin. (05 Mar 2000) |
| myeloma | <oncology, tumour> A malignant tumour composed of plasma cells of the type normally found in the bone marrow. (18 Nov 1997) |
| myeloma cell | <haematology, oncology> Neoplastic plasma cell. The proliferating plasma cells often replace all the others within the marrow, leading to immune deficiency and frequently there is destruction of the bone cortex. Because they are monoclonal in origin they secrete a monoclonal immunoglobulin. Bence Jones proteins are monoclonal immunoglobulin light chains overproduced by myeloma cells and excreted in the urine. Myeloma cell lines are used for producing hybridomas in raising monoclonal antibodies. (18 Nov 1997) |
| myeloma protein | <haematology, oncology> The immunoglobulins and Bence Jones proteins secreted by myeloma cells. (18 Nov 1997) |
| myelomalacia | Softening of the spinal cord. Origin: myelo-+ G. Malakia, a softness (05 Mar 2000) |
| myelomatosis | <oncology, tumour> See myeloma cell. (18 Nov 1997) |
| myelogenous |
Having to do with, produced by, or resembling the bone marrow. Sometimes used as a synonym for myeloid; for example, acute myeloid leukemia and acute myelogenous leukemia are the same disease.

| myeloid |
Having to do with or resembling the bone marrow. May also refer to certain types of hematopoietic (blood-forming) cells found in the bone marrow. Sometimes used as a synonym for myelogenous; for example, acute myeloid leukemia and acute myelogenous leukemia are the same disease.
