| sarcoma viruses, simian | Species of mammalian type c retroviruses (retroviruses type c, mammalian) producing tumours in primates. Originally isolated from a fibrosarcoma in a woolly monkey, ssv is a replication-defective v-onc virus which carries the sis oncogene. In order to propagate, ssv requires a replication-competent helper virus, simian sarcoma virus-associated virus (ssav). (12 Dec 1998) |
|---|---|
| sarcoma virus, feline | A species of mammalian type c retroviruses (retroviruses type c, mammalian) isolated from fibrosarcoma in cats. The virus is actually a recombinant feline leukaemia virus (felv) where part of the genome has been replaced by cellular oncogenes. It is unique to individuals and not transmitted naturally to other cats. Fesv is replication defective and requires felv to reproduce. (12 Dec 1998) |
| herpes virus, kaposi sarcoma-associated | Species of an unnamed genus, subfamily gammaherpesvirinae, isolated from patients with aids-related and "classical" kaposi sarcoma. The sequences suggest this is a new human herpes virus, unofficially identified as human herpes virus-8 (hhv-8). (12 Dec 1998) |
| pulmonary artery sarcoma | <radiology> Rare, age: 21 - 80 (most common: 45 - 55), usual presentation: hilar mass or hilar infiltrative lesion, other findings: decreased vascular markings, atelectasis / volume loss, metastatic nodules, decreased or absent perfusion on V/Q, intravascular soft-tissue mass on CT (12 Dec 1998) |
| soft tissue sarcoma | A sarcoma that begins in the muscle, fat, fibrous tissue, blood vessels, or other supporting tissue of the body. Not a type of bone cancer. (12 Dec 1998) |
| synovial sarcoma | <radiology> Soft-tissue mass, usually about 1 cm from joint, amorphous calcifications (33%), most common at knee, bone erosion (wide zone of transition), juxta-articular osteoporosis Cf: pigmented villonodular synovitis (PVS) (12 Dec 1998) |
| immunoblastic sarcoma | <tumour> Obsolete term for immunoblastic lymphoma. (05 Mar 2000) |
| osteogenic sarcoma | <oncology, tumour> A primary malignant bone cancer that arises from the cells which produce bone. It is most commonly seen in the second and third decades of life. Genetic factors appear to be important in the development of this illness. Paget's disease may be a predisposing cause. Treatment involves a combination of surgery and chemotherapy. (27 Sep 1997) |
| telangiectatic osteogenic sarcoma | <tumour> A lytic cystic variant of osteogenic sarcoma composed of aneurysmal blood-filled spaces lined by sarcoma cells producing osteoid. (05 Mar 2000) |
| endometrial stromal sarcoma | <tumour> A term sometimes used for a relatively rare sarcoma believed to be a form of endometriosis in which the lesions form multiple foci in the myometrium and in vascular spaces in other sites, and which consist of histologic and cytologic elements that resemble those of the endometrial stroma. Synonym: stromatosis. (05 Mar 2000) |
| Jensen's sarcoma | <tumour> A mouse tumour transmissible by inoculation. (05 Mar 2000) |
| 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) |
