| fimbriae of uterine tube | The irregularly branched or fringed processes surrounding the ampulla at the abdominal opening of the uterine tube; most of the lining epithelial cells have cilia that beat toward the uterus. Synonym: fimbriae tubae uterinae, laciniae tubae, Richard's fringes. (05 Mar 2000) |
| lower uterine segment | The inferior portion or isthmus of the uterus, the lower extremity of which joins with the cervical canal and, during pregnancy, expands to become the lower part of the uterine cavity. (05 Mar 2000) |
| lower uterine segment cesarean section | A cesarean section in which the uterus is entered in its lower segment by a transperitoneal approach. (05 Mar 2000) |
| alveolar soft part sarcoma | <tumour> A malignant tumour formed of a reticular stroma of connective tissue enclosing aggregates of large round or polygonal cells; occurs in subcutaneous and fibromuscular tissues. (05 Mar 2000) |
| ameloblastic sarcoma | <tumour> A rapidly growing, painful, destructive, radiolucent odontogenic tumour that usually arises through malignant change in the mesenchymal component of a pre-existing ameloblastic fibroma. Synonym: ameloblastic sarcoma. (05 Mar 2000) |
| angiolithic sarcoma | <tumour> A firm cellular neoplasm derived from fibrous tissue of the meninges, choroid plexus, and certain other structures associated with the brain, characterised by the formation of multiple, discrete, concentrically laminated, calcareous bodies (psammoma bodies); most of these neoplasms are histologically benign, but may lead to severe symptoms as a result of compressing the brain. Synonym: angiolithic sarcoma, sand tumour, Virchow's psammoma. (05 Mar 2000) |
| avian leukaemia-sarcoma complex | A term applied to a group of transmissible virus-induced diseases of chickens causing sarcoma, myeloblastosis, erythroblastosis, leukosis, osteopetrosis, and lymphomatosis. These agents are closely related viruses (avian leukosis-sarcoma virus) causing prolferation of immature erythroid, myeloid, or lymphoid cells, a division of the RNA tumour viruses (subfamily Oncovirinae) causing the avian leukosis-sarcoma complex of diseases; the viruses are subgrouped according to antigenic characteristics and growth in defined types of tissue culture cells. Synonym: avian erythroblastosis virus, avian leukosis-sarcoma virus, avian lymphomatosis virus, avian myeloblastosis virus, avian sarcoma virus, fowl erythroblastosis virus, fowl lymphomatosis virus, fowl myeloblastosis virus.

| avian leukosis-sarcoma virus | avian leukosis-sarcoma complex |
| avian 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) |
| avian sarcoma virus | avian leukosis-sarcoma complex |
| botryoid sarcoma | <tumour> A polypoid form of embryonal rhabdomyosarcoma which occurs in children, most frequently in the urogenital tract, characterised by the formation of grossly apparent grapelike clusters of neoplastic tissue that consist of rhabdomyoblasts, spindle, and stellate cells in a myxomatous stroma; neoplasms of this type grow relatively rapidly and are highly malignant. (05 Mar 2000) |
| giant cell monstrocellular sarcoma of Zulch | A histologic form of glioblastoma with large, often multinucleated, bizarre, tumour cells. Synonym: giant cell monstrocellular sarcoma of Zulch. (05 Mar 2000) |
| giant cell sarcoma | <tumour> A malignant giant cell tumour of bone. (05 Mar 2000) |
| medullary sarcoma | <tumour> A soft, extremely vascular sarcoma. (05 Mar 2000) |
