| acrodermatitis chronica atrophicans | A gradually progressive late skin manifestation of Lyme disease, appearing first on the feet, hands, elbows or knees, and comprised of indurated, erythematous plaques that become atrophic, giving a tissue-paper appearance of the involved sites. The disease is caused by Borrelia spirochetes, commonly transmitted by the Ixodes ricinus wood tick. (05 Mar 2000) |

| chondrodermatitis nodularis chronica helicis | A benign, chronic, small, painful nodule (or nodules) on the helix of the ear in elderly white males, which may occasionally become ulcerated. Synonym: Winkler's disease. (05 Mar 2000) |
| pityriasis lichenoides chronica | An eruption lasting up to a few years, of reddish-brown papules with central scaling, that clears without scarring. Origin: Lichenoides Mod. L., fr. G. Leichen, lichen, a lichen-like eruption, + eidos, resemblance chronica Mod. L. Chronic, fr. G. Chronikos, pertaining to time; fr. Chronos, time (05 Mar 2000) |
| polyarthritis chronica | An obsolete term for rheumatoid arthritis. (05 Mar 2000) |
| polyarthritis chronica villosa | A chronic inflammation confined to the synovial membrane, involving a number of joints; it occurs in women at the menopause and in children. (05 Mar 2000) |
| mycosis cutis chronica | A chronic dermatomycosis caused by a fungus. (05 Mar 2000) |
| encephalitis subcorticalis chronica | One of the causes of multiinfarct dementia, in which there are many infarcts and lacunes in the white matter, with relative sparing of the cortex and basal ganglia. Synonym: Binswanger's encephalopathy, encephalitis subcorticalis chronica, subcortical arteriosclerotic encephalopathy. (05 Mar 2000) |
| urticaria chronica | A form of urticaria in which the wheals recur frequently, or persist. Synonym: urticaria chronica. (05 Mar 2000) |
| avian erythroblastosis | <veterinary> An expression of disease of the avian leukosis-sarcoma complex; characterised by severe anaemia and large numbers of erythroblasts in the blood; chickens are most susceptible but fatal natural infections have been reported in guinea fowl. Synonym: fowl erythroblastosis. (05 Mar 2000) |
| avian erythroblastosis virus | <virology> Group of C type RNA tumour viruses (Oncovirinae) that cause various leukaemias and other tumours in birds. The acute leukaemia viruses, that are replication defective and require helper viruses, include avian erythroblastosis (AEV), myeloblastosis (AMV) and myelo cytomatosis viruses. AEV carries two transforming genes, v erbA and v erbB, the cellular homologue of the latter is the structural gene for the epidermal growth factor receptor. AMV carries v myb and causes a myeloid leukaemia, avian myelocytomatosis virus carries v myc. The avian lymphatic leukaemia viruses (ALV) are also Retroviridae but are replication competent and induce neoplasia only after several months, they often occur in conjunction with replication defective leukaemia viruses.

| erythroblastosis | The presence of erythroblasts in considerable number in the blood. Origin: erythroblast + -osis, condition (05 Mar 2000) |
| erythroblastosis, foetal | Haemolytic anaemia of the foetus or newborn infant, caused by the transplacental transmission of maternally formed antibody, usually secondary to an incompatibility between the blood group of the mother and that of her offspring. (12 Dec 1998) |
| erythroblastosis foetalis | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
| erythroblastosis virus, avian | A species of avian type c retroviruses (retroviruses type c, avian) causing progressive anaemia and weakness in domestic and wild fowl. (12 Dec 1998) |
| foetal erythroblastosis | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
