| acute monocytic leukaemia | <haematology> The most common translocation in this disorder of poorly differentiated monocytic cells involves chromosome region 11q in a large percentage of cases. The translocation involves a cellular oncogene, c-ets which is mapped to the 11q23-24 region. The most common translocations reported are t(6;11), t(9;11), t(11;17) and t(11;19), of which t(9;11) (p21-22;q23) is by far the most frequently detected and implicated in acute myeloid leukaemia. The cells express CD14 surface antigen, which is diagnostic of monocytic cells. Acronym: AML Classification: FAB M5 (07 Apr 1998) |

| monocytic leukaemia | Cancer of the blood due to proliferation of cells of the monocyte series. Origin: Gr. Haima = blood (13 Nov 1997) |
| Schilling type of monocytic leukaemia | See: monocytic leukaemia. (05 Mar 2000) |
| Naegeli type of monocytic leukaemia | A variant of granulocytic leukaemia with monocytosis in the peripheral blood. Synonym: Naegeli type of monocytic leukaemia. (05 Mar 2000) |
| chronic granulocytic leukaemia | <haematology> A leukaemia which is initially slowly-progressing. There are approximately 650 new cases each year in the UK. It is characterised by the presence of large numbers of abnormal mature granulocytes, circulating in the blood. Synonym: chronic granulocytic leukaemia. Acronym: CML Origin: Gr. Haima = blood (12 Jan 1998) |
| chronic leukaemia | A persistent cancer of the blood, usually of gradual onset and generally of slow progression. May be diagnosed by chance following a routine blood test and prior to the appearance of clinical symptoms. Origin: Gr. Haima = blood (13 Nov 1997) |
| chronic lymphocytic leukaemia | <haematology> A slowly progressing form of leukaemia, characterised by an increased number of the type of white blood cell known as lymphocytes. With about 3, 500 new cases occurring each year in the UK, it is the most common form of leukaemia and occurs predominantly in late middle age onwards. It has variable symptoms and course, but may be diagnosed by chance before the patient develops any clinical symptoms of disease. Acronym: CLL Origin: Gr. Haima = blood (12 Jan 1998) |
| chronic myeloid leukaemia | <haematology> A leukaemia which is initially slowly-progressing. There are approximately 650 new cases each year in the UK. It is characterised by the presence of large numbers of abnormal mature granulocytes, circulating in the blood. Synonym: chronic granulocytic leukaemia. Acronym: CML Origin: Gr. Haima = blood (12 Jan 1998) |
| chronic myelomonocytic leukaemia | <haematology> A form of myelodysplasia characterised by an increase in the number of circulating white blood cells of the monocyte type. Acronym: CMML Origin: Gr. Haima = blood (12 Jan 1998) |
| monocytic angina | An obsolete term for infectious mononucleosis. (05 Mar 2000) |
| monocytic leukemoid reaction | Leukocytosis of varying degree, e.g., 30,000 to 40,000 per cu mm, with adult monocytes and immature forms amounting to 30% (or more) of the total number of white blood cells in the circulating blood; may be observed in association with tuberculosis, especially the first infection, miliary type. (05 Mar 2000) |
| monocytic leukocytosis | An abnormal increase in the number of monocytes in the circulating blood. Synonym: monocytic leukocytosis. (05 Mar 2000) |
| monocytic leukopenia | Diminution in the number of monocytes in the circulating blood. Synonym: monocytic leukopenia, monopenia. Origin: mono-+ G. Kytos, cell, + penia, poverty (05 Mar 2000) |
| equine monocytic ehrlichiosis | <veterinary> A febrile disease of horses in North America caused by Ehrlichia risticii and characterised by anorexia, leukopenia, and occasional diarrhoea. Synonym: Potomac horse fever. (05 Mar 2000) |
