| ewing sarcoma | <radiology> Small, round-cell sarcoma of mesenchyme of medullary bone, age 5 - 14 yrs, most lethal of all primary bone tumours, any bone, less than 20 years of age: long bones, greater than 20 years of age: flat bones (where there's still red marrow), purely lytic (62%), purely sclerotic (15%), periosteal reaction (onion-skin or perpendicular), similar lesion at different age, less than 5 years of age -- neuroblastoma, greater than 30 years of age -- metastasis, reticulum cell sarcoma (12 Dec 1998) |
| Ewing's sarcoma | <oncology, tumour> A malignant primary bone tumour that arises most commonly in the first three decades of life. It is highly malignant (prone to spread) and often requires treatment with some combination of radiation therapy and chemotherapy. (27 Sep 1997) |
| juxtacortical osteogenic sarcoma | <tumour> A form of osteogenic sarcoma of relatively low malignancy, probably arising from the periosteum and initially involving cortical bone and adjacent connective tissue, which occurs in middle-aged as well as young adults and most commonly affects the lower part of the femoral shaft. Synonym: periosteal sarcoma. (05 Mar 2000) |
| Kaposi sarcoma | <oncology, tumour> A sarcoma of spindle cells mixed with angiomatous tissue. A relatively rare malignant skin tumour that results in multifocal purplish coloured papules or plaques that eventually form nodules. Usually classed as an angioblastic tumour. Seen most commonly in patients who suffer from AIDS. Tumours may also occur within the intestines and lungs. Diagnosis may be confirmed with skin biopsy or upper GI endoscopy. Radiation therapy, cryotherapy and chemotherapy have all been used in the treatment of Kaposi sarcoma. (27 Sep 1997) |
| Kaposi sarcoma associated herpesvirus protease | <enzyme> Genbank af010430 Registry number: EC 3.4.21.- Synonym: kshv protease, human herpesvirus 8 protease (26 Jun 1999) |
| kaposi's sarcoma | <oncology, tumour> A type of vascular cancer characterised by soft purple nodules that usually develop first on the feet and then slowly spread across the skin.This cancer is most often found in people with compromised immune systems, such as AIDS patients. (09 Oct 1997) |
| fascicular sarcoma | <tumour> A malignant neoplasm, believed to be of mesenchymal origin, composed of elongated, spindle-shaped cells. Synonym: fascicular sarcoma. (05 Mar 2000) |
| undifferentiated sarcoma of liver | <radiology> Kiddies, age 4 - 15 yrs, M = F, complex hepatic mass, often hypovascular, most in right lobe, large ( more than 10 cm), ** Differential diagnosis: embryonal rhabdomyosarcoma (12 Dec 1998) |
| Kirsten sarcoma virus | <virology> A murine sarcoma inducing retrovirus, generated by passaging a murine erythoblastosis virus in newborn rats. Source of the Ki ras oncogene. (18 Nov 1997) |
| feline sarcoma | <oncology, tumour> An oncogene carried by one of the strains of the feline sarcoma virus (the Snyder-Theilen strain, Garden-Rasheed strain, McDonough strain). It causes the development of sarcoma tumours in cats. The normal product of the gene (as a proto-oncogene) seems to be a kinase enzyme that phosphorylates (attaches phosphate groups to) the amino acid tyrosine in polypeptides. (09 Oct 1997) |
| feline sarcoma virus | <virology> A retrovirus which carries an oncogene that causes feline sarcoma (a tumour-causing disease) in cats. (09 Oct 1997) |
| leukocytic sarcoma | <haematology> An acute or chronic disease of unknown cause in man and other warm blooded animals that involves the blood forming organs, is characterised by an abnormal increase in the number of leucocytes in the tissues of the body with or without a corresponding increase of those in the circulating blood and is classified according of the type leucocyte most prominently involved. (18 Nov 1997) |
| lymphatic sarcoma | <tumour> Obsolete term for lymphosarcoma. (05 Mar 2000) |
