| mixed tumour | A tumour composed of two or more varieties of tissue. (05 Mar 2000) |
|---|---|
| mixed tumour, mesodermal | A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. It is associated with previous pelvic radiation exposure in 20% of patients. (12 Dec 1998) |
| mixed tumour, mullerian | A tumour, basically a carcinoma with a single sarcoma such as leiomyosarcoma or angiosarcoma or multiple sarcomas of uterine origin. The role of oestrogen has been postulated as a possible aetiological factor in this tumour. (holland et al., cancer medicine, 3d ed, p1703) (12 Dec 1998) |
| mixed tumour of salivary gland | A tumour composed of salivary gland epithelium and fibrous tissue with mucoid or cartilaginous areas. Synonym: pleomorphic adenoma. (05 Mar 2000) |
| mixed tumour of skin | <tumour> A benign tumour of sweat glands with a mucoid stroma showing cartilaginous metaplasia. Synonym: mixed tumour of skin. (05 Mar 2000) |
| Codman's tumour | Chondroblastoma of the proximal humerus. (05 Mar 2000) |
| Warthin's tumour | <oncology, tumour> A benign tumour characterised histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid. (25 Jun 1999) |
| pilar tumour of scalp | A solitary tumour of the scalp in elderly women that may ulcerate; microscopically resembles squamous cell carcinoma composed of glycogen-rich clear cells, but is benign. Synonym: proliferating tricholemmal cyst. (05 Mar 2000) |
| Pindborg tumour | A benign epithelial odontogenic neoplasm derived from the stratum intermedium of the enamel organ; a painless, slowly growing, mixed radiolucent-radiopaque lesion characterised histologically by cords of polyhedral epithelial cells, deposits of amyloid, and spherical calcifications. Synonym: Pindborg tumour. (05 Mar 2000) |
| Pinkus tumour | <tumour> A skin tumour composed of fibrous tissue intersected by thin anastomosing bands of basal cells of the epidermis; may give rise to basal cell carcinoma of the nodular type. Synonym: Pinkus tumour. (05 Mar 2000) |
| collision tumour | Two originally separate tumour's, especially a carcinoma and a sarcoma, that appear to have developed by chance in close proximity, so that an area of mingling exists. See: carcinosarcoma. (05 Mar 2000) |
| placental site trophoblastic tumour | A tumour usually arising in the uterus of parous women during reproductive years. Histologically, the tumour consists of a predominance of intermediate trophoblastic cells with fibrinoid material and vascular invasion. (05 Mar 2000) |
| mouse mammary tumour virus | Member of the retrovirus subfamily Oncornavirinae, antigenically distinct from the murine leukaemia-sarcoma complex, that is associated with adenocarcinomatous tumours of the mammary gland, commonly latent in wild and laboratory mice and causing cancer only in genetically susceptible strains under certain hormonal influences. Synonym: Bittner agent, Bittner virus, Bittner's milk factor, mammary cancer virus of mice, milk factor, mouse mammary tumour virus. (05 Mar 2000) |
| mouse parotid tumour virus | <virology> A papovavirus (genus Polyomavirus, family Papovaviridae) which is a DNA tumour virus with very small genome. Polyoma was isolated from mice, in which it causes no obvious disease, but when injected at high titre into baby rodents, including mice, it causes tumours of a wide variety of histological types (hence polyoma). In vitro, infected mouse cells are permissive for virus replication and thus are killed, whilst hamster cells undergo abortive infection and at a low frequency become transformed. It is capable of producing parotid tumours in mice and sarcomas in hamsters as well as tumours in other laboratory animals. Synonym: mouse parotid tumour virus. (22 Sep 2002) |
| wilms tumour | <radiology> Nephroblastoma, 3rd most common kiddie tumour (most common abdominal tumour), arises from embryonal renal tissue (nephroblastomatosis), large, only 10% are calcified, 4-10% bilateral, metastasis may lead to lungs, para-aortic nodes associated with: aniridia, Beckwith-Wiedemann syndrome, hemihypertrophy, Drash syndrome Cf: neuroblastoma (more likely calcified) (12 Dec 1998) |
