| AMM | Agnogenic Myeloid Metaplasia |
| leukaemia, nonlymphocytic, acute | Acute leukaemia distinguished from acute lymphocytic leukaemia (all) by the morphology of the marrow and blood leukaemic cells. Cytoplasmic granules are usually present and the nucleus is usually large and irregular. Anll is more common in adults than all and occurs at any age. (12 Dec 1998) |

| agnogenic 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 | Collective term for the nonlymphocyte groups of white blood cells. It includes cells from the granulocyte, monocyte and platelet lineages. (13 Nov 1997) |
| myeloid cell | <haematology, pathology> One of the two classes of marrow derived blood cells, includes megakaryocytes, erythrocyte precursors, mononuclear phagocytes and all the polymorphonuclear granulocytes. That all these are ultimately derived from one stem cell lineage is shown by the occurrence of the Philadelphia chromosome in these, but not lymphoid, cells. most authors tend, however, to restrict the term myeloid to mononuclear phagocytes and granulocytes and commonly distinguish a separate erythroid lineage.

| 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) |
| primary myeloid metaplasia | Myeloid metaplasia occurring as the primary condition, often in association with myelofibrosis. Synonym: agnogenic myeloid metaplasia. (05 Mar 2000) |
| secondary myeloid metaplasia | Myeloid metaplasia occurring in individuals with another disease. Synonym: symptomatic myeloid metaplasia. (05 Mar 2000) |
| symptomatic myeloid metaplasia | Myeloid metaplasia occurring in individuals with another disease. Synonym: symptomatic myeloid metaplasia. (05 Mar 2000) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (05 Mar 2000) |
| accelerated phase of leukaemia | Refers to chronic myelogenous leukaemia that is progressing. The number of immature, abnormal white blood cells in the bone marrow and blood is higher than in the chronic phase, but not as high as in the blast phase. (12 Dec 1998) |
| adult T-cell leukaemia | Lymph nodes show a mixture of small and large atypical cells which are polymorphic and express nuclear pleiomorphism. Adult T-cell leukaemia is caused by HTLV-1 and is rare in the US and Europe but common in Japan. Tumour cells express CD2, CD3, CD5 and lack CD7. The most common chromosome change reported in adult T-cell leukaemia is presence of the 14q + marker (05 Mar 2000) |
