| periosteal 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) |

| round cell sarcoma | <tumour> Old term for an undifferentiated malignant neoplasm, believed to be of mesenchymal origin, composed chiefly of closely packed round cells. (05 Mar 2000) |
| Rous sarcoma | <tumour> A fibrosarcoma, originally observed in a Plymouth Rock hen, now thought to be an expression of infection by certain viruses of the avian leukosis-sarcoma complex in the family Retroviridae. Synonym: avian sarcoma, Rous tumour. (05 Mar 2000) |
| 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) |
| 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) |
| 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) |
| sarcoma, endometrial stromal | A highly malignant neoplasm of the endometrium, arising from the endometrial stroma. It represents one type of stromal tumour, the other being endolymphatic stromal myosis. They are differentiated on the basis of the number of mitoses per 10 high power fields: endometrial stromal sarcoma has 10 or more mitoses, endolymphatic stromal myosis fewer. Stroma sarcoma is seen most often between the ages of 45 and 50. (devita jr et al., cancer: principles & practice of oncology, 3d ed, p1146) (12 Dec 1998) |
| sarcoma, ewing's | A malignant tumour of the bone which always arises in the medullary tissue, occurring more often in cylindrical bones. There are conspicuous foci of necrosis in association with irregular masses of small, regular, rounded or ovoid cells with very scanty cytoplasm. The tumour occurs usually before the age of 20, about twice as frequently in males as in females. (12 Dec 1998) |
| sarcoma growth factor | <growth factor> Polypeptide released by sarcoma cells that promotes the growth of cells by binding to a cell surface receptor, the sarcoma cell is therefore self sufficient and independent of normal growth control. See: growth factors. The name is no longer commonly used. (18 Nov 1997) |
