|---|---|
| Moloney murine sarcoma virus | <molecular biology, virology> Replication defective retrovirus, source of the oncogene v mos, responsible for inducing fibrosarcomas in vivo and transforming cells in culture. (18 Nov 1997) |
| moloney sarcoma virus | A replication-defective murine sarcoma virus (sarcoma viruses, murine) isolated from a rhabdomyosarcoma by moloney in 1966. (12 Dec 1998) |
| multiple idiopathic haemorrhagic 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) |
| murine sarcoma virus | A seemingly defective retrovirus that produces sarcomas in mice when growing in the presence of a "helper" virus; e.g., mouse leukaemia virus. (05 Mar 2000) |
| myelogenic sarcoma | <tumour> Sarcoma originating in the bone marrow. (05 Mar 2000) |
| myeloid sarcoma | <tumour> A malignant tumour of immature myeloid cells, frequently subperiosteal, associated with or preceding granulocytic leukaemia. See: chloroma. Synonym: myeloid sarcoma. (05 Mar 2000) |
| porcine sarcoma virus | A retrovirus causing sarcoma in swine. (05 Mar 2000) |
| Harvey sarcoma virus | <oncogene> One of a family of oncogenes, first identified as transforming genes of Harvey and Kirsten murine sarcoma viruses. (Name from rat sarcoma because Harvey virus, though a mouse virus, obtained its transforming gene during passage in a rat). Transforming protein coded is p21ras, a GTP-binding protein with GTPase activity, that resembles regulatory G-proteins. (18 Nov 1997) |
| sarcoma | <oncology, tumour> A form of cancer that arises in the supportive tissues such as bone, cartilage, fat or muscle. Kaposi sarcoma: a sarcoma of spindle cells mixed with angiomatous tissue. Usually classed as an angioblastic tumour. A fairly frequent concomitant to HIV. Infection or long term immunosuppresion. (14 May 1997) |
| sarcoma, alveolar soft part | A variety of sarcoma having a reticulated fibrous stroma enclosing groups of sarcoma cells, which resemble epithelial cells and are enclosed in alveoli walled with connective tissue. It is a rare tumour, usually occurring between 15 and 35 years of age. It appears in the muscles of the extremities in adults and most commonly in the head and neck region of children. Though slow-growing, it commonly metastasizes to the lungs, brain, bones, and lymph nodes. (12 Dec 1998) |
| sarcoma, avian | Connective tissue tumours, affecting primarily fowl, that are usually caused by avian sarcoma viruses. (12 Dec 1998) |
| sarcoma botryoides | <radiology> Type of embryonal rhabdomyosarcoma, mass resembles bunch of grapes, originates submucosally, grows into lumen (12 Dec 1998) |
| sarcoma cell | Cells of a malignant tumour derived from connective tissue. Often given a prefix denoting tissue of origin, for example osteosarcoma (from bone). (18 Nov 1997) |
| sarcoma, clear cell | A sarcoma of young, often female, adults of the lower extremities and acral regions, intimately bound to tendons as circumscribed but unencapsulated melanin-bearing tumours of neuroectodermal origin. An ultrastructural finding simulates flattened and curved barrel staves, corresponding to the internal structures of premelanosomes. There is a 45-60% mortality in clear cell sarcoma. (12 Dec 1998) |
