| ascites | <clinical sign, gastroenterology> An effusion and accumulation of serous fluid in the abdominal cavity. Synonym: abdominal dropsy, peritoneal dropsy, hydroperitonia, hydrops abdominis. Origin: L, Gr. Askites from askos = bag (18 Nov 1997) |
|---|---|
| ascites adiposus | <gastroenterology> A large collection of lymph fluid in the abdominal cavity, sometimes secondary to blockage of the main lymph duct or injury to it. (27 Sep 1997) |
| ascites in neonates | <radiology> Urine, urethral valves, UPJ or UVJ obstruction, oedema: erythroblastalis foetalis, portal vein obstruction, hypoproteinaemia, pus, peritonitis, syphilis, meconium peritonitis, gastrointestinal contents, perforation, meconium peritonitis, blood, trauma, rupture of spleen or liver, chyle, chylous ascites, lymphangiectasia, bile, common bile duct obtruction, perforation, ruptured cyst, ovarian cyst, omental cyst, choledochal cyst (12 Dec 1998) |
| ascites tumour | <oncology> Tumour that grows in the peritoneal cavity as a suspension of cells. Obviously such cells have lost anchorage dependence and they can easily be isolated and passaged. Hybridomas are sometimes grown as ascites tumours and the ascites fluid can then be used as the crude antiserum. (18 Nov 1997) |
| gelatinous ascites | <radiology> Rupture of: ovarian pseudomucinous cystadenoma, appendicial mucocele, mucinous material in peritoneum, with or without diffuse abdominal calcification (12 Dec 1998) |
| chyliform ascites | <gastroenterology> A large collection of lymph fluid in the abdominal cavity, sometimes secondary to blockage of the main lymph duct or injury to it. (27 Sep 1997) |
| chylous ascites | <gastroenterology> A large collection of lymph fluid in the abdominal cavity, sometimes secondary to blockage of the main lymph duct or injury to it. (27 Sep 1997) |
| milky ascites | <gastroenterology> A large collection of lymph fluid in the abdominal cavity, sometimes secondary to blockage of the main lymph duct or injury to it. (27 Sep 1997) |
| haemorrhagic ascites | Bloody or blood-stained serous fluid, frequently resulting from metastatic carcinoma, in the peritoneal cavity. (05 Mar 2000) |
| pseudochylous ascites | Presence in the peritoneum of an opalescent or cloudy fluid that does not contain fat. (05 Mar 2000) |
| fatty ascites | <gastroenterology> A large collection of lymph fluid in the abdominal cavity, sometimes secondary to blockage of the main lymph duct or injury to it. (27 Sep 1997) |
| cancer, malignant melanoma | A skin cancer that begins in cells called melanocytes that can grow together to form benign (not cancerous) moles. A change in size, shape, or colour of a mole can be a sign of melanoma. Melanoma can be cured if detected early, before spread (metastasis) to other areas of the body. Diagnosis is confirmed with a biopsy of the abnormal skin. Sun exposure can cause skin damage that can lead to melanoma. (12 Dec 1998) |
| canine malignant lymphoma | <tumour> A progressive fatal disease of dogs characterised by neoplastic transformation and proliferation of lymphoid cells, usually originating in solid lymphoid organs (lymphosarcoma) or bone marrow (lymphocytic leukaemia). (05 Mar 2000) |
| malignant | <oncology> Tending to become progressively worse and to result in death. Having the properties of anaplasia, invasion and metastasis, said of tumours. Origin: L. Malignans = acting maliciously (18 Nov 1997) |
| malignant anaemia | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
