| leukodystrophia | Synonym: leukodystrophy. (05 Mar 2000) |
| leukodystrophia cerebri progressiva | <radiology> Type of dysmyelinating disease, hereditary, peripheral nervous system unaffected in some disorders Specific diseases: adrenoleukodystrophy, metachromatic leukodystrophy, spongy degeneration (Canavan), globoid cell (Krabbe) leukodystrophy, Alexander disease, Pelizaeus-Merzbacher disease, Cockayne syndrome (12 Dec 1998) |

| leukodystrophy with diffuse Rosenthal fibre formation | A metabolic disorder whose onset can be in infancy, adolescence, or adulthood; characterised pathologically by widespread cerebral demyelination with astrocyte and primitive oligodendroglial cell proliferation; refractile Rosenthal fibres result from the degeneration of these proliferating cells; aetiology unknown, but possibly due to a metabolic defect of astrocytes; sex-linked recessive disorder. (05 Mar 2000) |
| leukodystrophy, globoid cell | An inherited metabolic disorder of the nervous system, particularly the white matter. It is characterised histologically by a paucity of myelin and oligodendroglia, severe astrocytic gliosis, and massive infiltration with unique multinucleated globoid cells which are enriched in galactosylceramide. The primary genetic defect is a deficiency of galactosylceramidase. (12 Dec 1998) |
| leukodystrophy, metachromatic | A sphingolipidosis where there is defective desulfation of galactosyl-3-sulfate ceramide due to a defective enzyme cerebroside sulfatase (arylsulfatase a). The result is an accumulation of sulfatide in neural and non-neural tissues which manifests as mental deterioration and severe disturbances of the central nervous system. (12 Dec 1998) |
| leukoedema | A bluish-white opalescence of the buccal mucosa which becomes the normal mucosal colour on stretching the tissue; most commonly observed in blacks and may be considered a normal anatomic variation. (05 Mar 2000) |
| leukoedema, oral | A disorder of the buccal mucosa resembling early leukoplakia, characterised by the presence of filmy opalescence of the mucosa in the early stages to a whitish gray cast with a coarsely wrinkled surface in the later stages, associated with intracellular oedema of the spinous or malpighian layer. (12 Dec 1998) |
| leukoencephalitis | Encephalitis restricted to the white matter. (05 Mar 2000) |
| leukoencephalitis, acute haemorrhagic | A rare, fatal postinfection or allergic demyelinating disease of the central nervous system having a fulminating course and occurring mainly in young adults. It is characterised by destruction of white matter to the point of liquefaction; widespread necrosis of blood vessel walls leading to the formation of multiple small haemorrhages in the involved areas and the exudation of fibrin into the surrounding tissue; and cellular infiltration of the necrotic areas. (12 Dec 1998) |
| leukoencephalopathy | White matter changes first described in children with leukaemia, associated with radiation and chemotherapy injury, often associated with methotrexate; pathologically characterised by diffuse reactive astrocytosis with multiple areas of necrotic foci without inflammation. Origin: Leuko-+ G. Enkephalos, brain, + pathos, suffering (05 Mar 2000) |
| leukoencephalopathy, progressive multifocal | Rare demyelinating disease of the central nervous system which develops in immunocompromised patients secondary to lymphoproliferative disease, immunosuppressive therapy, autoimmune disorders, or aids. It is caused by the jc virus, a polyomavirus. (12 Dec 1998) |
| leukoerythroblastic anaemia | <haematology> Any anaemia condition which arises from a space occupying lesion in the bone marrow. The circulating blood contains immature cells of the granulocytic series and nucleated red blood cells, frequently in numbers that are disproportionately large in relation to the degree of anaemia. Origin: Gr. Haima = blood (27 Sep 1997) |
| leukoerythroblastosis | Any anaemic condition resulting from space-occupying lesions in the bone marrow; the circulating blood contains immature cells of the granulocytic series and nucleated red blood cells, frequently in numbers that are disproportionately large in relation to the degree of anaemia. Synonym: leukoerythroblastic anaemia, myelophthisic anaemia, myelopathic anaemia. (05 Mar 2000) |
