| 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, lymphocytic | Leukaemia associated with hyperplasia and overactivity of the lymphoid tissue. There are increased numbers of circulating malignant lymphocytes and lymphoblasts. (12 Dec 1998) |
| leukaemia, masT-cell | A disorder characterised by the presence of large numbers of tissue mast cells in the peripheral blood. (12 Dec 1998) |
| leukaemia, megakaryocytic, acute | Nonlymphocytic leukaemia in which 20-30% of the bone marrow or peripheral blood cells are of megakaryocyte lineage. Myelofibrosis or increased bone marrow reticulin is common. (12 Dec 1998) |
| leukaemia, myelocytic, acute | Progressive, malignant disease of the myeloid tissue in which the granular, polymorphonuclear leukocytes and their precursors predominate. (12 Dec 1998) |
| leukaemia, myeloid | Form of leukaemia characterised by an uncontrolled proliferation of the myeloid lineage and their precursors in the bone marrow and other sites. (12 Dec 1998) |
| 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) |
| leukaemia, smoldering | A condition in which the bone marrow does not function normally. It does not produce enough blood cells. This condition may progress and become acute leukaemia. Smoldering leukaemia also is called myelodysplastic syndrome or preleukaemia. (12 Dec 1998) |
| leukaemic | Pertaining to, or having the characteristics of, any form of leukaemia. (05 Mar 2000) |
| leukaemic hyperplastic gingivitis | Enlarged gingiva due to infiltration of leukaemic cells and infection from local factors in the face of diminshed host response. (05 Mar 2000) |
| leukaemic infiltration | A pathologic change in leukaemia in which leukaemic cells permeate various organs at any stage of the disease. All types of leukaemia show various degrees of infiltration, depending upon the type of leukaemia. The degree of infiltration may vary from site to site. The liver and spleen are common sites of infiltration, the greatest appearing in myelocytic leukaemia, but infiltration is seen also in the granulocytic and lymphocytic types. The kidney is also a common site and of the gastrointestinal system, the stomach and ileum are commonly involved. In lymphocytic leukaemia the skin is often infiltrated. The central nervous system too is a common site. (12 Dec 1998) |
| leukaemic leukaemia | A redundant term sometimes used to emphasize the occurrence of abundant numbers of leukaemic cells in the circulating blood; this classic form of leukaemia is usually termed simply leukaemia. (05 Mar 2000) |
| leukaemic myelosis | <haematology, tumour> A form of leukaemia characterised by an uncontrolled proliferation of myelopoietic cells in the bone marrow and in extramedullary sites, and the presence of large numbers of immature and mature granulocytic forms in various tissues (and organs) and in the circulating blood. The total count may range from 1000 (aleukaemic variety) to several hundred thousand per cu mm. The predominant cell is usually of the neutrophilic series, but, in a few instances, eosinophilic or basophilic granulocytes, or even megakaryocytes, may represent the chief form; early in granulocytic leukaemia, the circulating blood may contain excessive numbers of all of the granulocytic forms. Synonym: leukaemic myelosis, myelocytic leukaemia, myelogenic leukaemia, myelogenous leukaemia, myeloid leukaemia. (05 Mar 2000) |
