| stem cell leukaemia | A form of leukaemia in which the abnormal cells are thought to be the precursors of lymphoblasts, myeloblasts, or monoblasts. Synonym: embryonal leukaemia. (05 Mar 2000) |
|---|---|
| neutrophilic leukaemia | An unusual form of chronic granulocytic leukaemia in which the greatly increased number of leukocytes in the circulating blood are mature polymorphonuclear neutrophils, with virtually no young or immature granulocytes being observed. (05 Mar 2000) |
| subleukaemic leukaemia | A form of leukaemia in which abnormal cells are present in the peripheral blood, but the total leukocyte count is not elevated. Synonym: hypoleukaemia, leukopenic myelosis, subleukaemic myelosis, subleukaemia. (05 Mar 2000) |
| embryonal leukaemia | A form of leukaemia in which the abnormal cells are thought to be the precursors of lymphoblasts, myeloblasts, or monoblasts. Synonym: embryonal leukaemia. (05 Mar 2000) |
| eosinophilic leukaemia | Eosinophilocytic leukaemia, a form of granulocytic leukaemia in which there are conspicuous numbers of eosinophilic granulocytes in the tissues and circulating blood, or in which such cells are predominant; in chronic disease of this type, the total white blood cell count may be as high as 200,000 to 250,000 per cu mm, with as many as 80 or 90% being eosinophils, chiefly adult forms. (05 Mar 2000) |
| feline leukaemia | A leukaemic disorder of cats caused by feline leukaemia virus, a member of the family Retroviridae, and characterised by depression and mild fever, and by the presence of tumours in the mediastinal and mesenteric lymph nodes, followed by multiple tumour formation throughout the body; during the terminal stages of the disease lymphoblasts may appear in the peripheral blood. (05 Mar 2000) |
| leukaemia | <haematology> An acute or chronic disease of unknown cause in man and other warm blooded animals that involves the blood forming organs, is characterised by an abnormal increase in the number of leucocytes in the tissues of the body with or without a corresponding increase of those in the circulating blood and is classified according of the type leucocyte most prominently involved. (18 Nov 1997) |
| leukaemia, accelerated phase of | 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) |
| leukaemia, calla-positive | Acute leukaemia in which lymphocytes are positive for the common acute lymphoblastic leukaemia antigen (calla). (12 Dec 1998) |
| leukaemia cutis | Yellow-brown, red, blue-red, or purple, sometimes nodular lesions associated with diffuse infiltration of leukaemic cells in the skin; the involvement may be diffuse and generalised, i.e., so-called universal leukaemia cutis, or it may be localised. (05 Mar 2000) |
| leukaemia, erythroblastic, acute | A myeloproliferative disorder characterised by neoplastic proliferation of erythroblastic and myeloblastic elements with atypical erythroblasts and myeloblasts in the peripheral blood. (12 Dec 1998) |
| leukaemia, experimental | Leukaemia induced experimentally by administration of various leukemogenic agents, viruses, radiation or transplantation. (12 Dec 1998) |
| leukaemia, feline | A neoplastic disease of cats frequently associated with feline leukaemia virus infection. (12 Dec 1998) |
| leukaemia, hairy cell | A neoplastic disease of the lymphoreticular cells which is considered to be a rare type of chronic leukaemia; it is characterised by an insidious onset, splenomegaly, anaemia, granulocytopenia, thrombocytopenia, little or no lymphadenopathy, and the presence of "hairy" or "flagellated" cells in the blood and bone marrow. (12 Dec 1998) |
| Leukaemia inhibitory factor | <growth factor> Polypeptide growth factor or cytokine with wide range of activities. Regulates growth and differentiation of primordial germ cells and embryonic stem cells but has effects on peripheral neurons, osteoblasts, adipocytes and various cells of the myeloid lineage. Given to adult animals induces weight loss, behavioural disorders and bone abnormalities. Many of the effects of LIF in vitro can be mimicked by IL-6, oncostatin M and ciliary neurotrophic factor, all of which interact indirectly with gp130, a shared tranducer subunit. (18 Nov 1997) |
