| adrenal rest tumour | A rare, usually benign, ovarian tumour thought to be derived from embryonic rest cells of the adrenals. This tumour causes various degrees of masculinization. (12 Dec 1998) |
|---|---|
| ameloblastic adenomatoid tumour | A benign epithelial odontogenic tumour appearing radiographically as a well-circumscribed radiolucent-radiopaque lesion usually surrounding the crown of an impacted tooth in an adolescent or young adult; characterised histologically by columnar cells organised in a duct-like configuration interspersed with spindle-shaped cells and amyloid-like deposition that gradually undergoes dystrophic calcification. Synonym: adenoameloblastoma, ameloblastic adenomatoid tumour. (05 Mar 2000) |
| amyloid tumour | A localised form of amyloidosis in which amyloid occurs as masses or nodules beneath the skin or mucous membranes, e.g., in the larynx. Synonym: amyloid tumour, focal amyloidosis. (05 Mar 2000) |
| angiomatoid tumour | A small, circumscribed, benign tumour of the genital tract, composed of small glandlike spaces lined by flattened or cuboidal mesothelium-like cells. (12 Dec 1998) |
| antigens, tumour-associated, carbohydrate | Carbohydrate antigens expressed by malignant tissue. They are useful as tumour markers and are measured in the serum by means of a radioimmunoassay employing monoclonal antibodies. (12 Dec 1998) |
| antigens, viral, tumour | Those proteins recognised by antibodies from serum of animals bearing tumours induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation. (12 Dec 1998) |
| aortic body tumour | Aortic body, carotid body, chemoreceptor, or glomus jugulare tumour; nonchromaffin paraganglioma; receptoma; a relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body, glomus jugulare, and aortic bodies; consisting histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. Compare: paraganglioma. Synonym: aortic body tumour, carotid body tumour, chemoreceptor tumour, glomus jugulare tumour, nonchromaffin paraganglioma. Origin: chemo-+ G. Dektes, receiver, fr. Dechomai, to receive, + -oma, tumour (05 Mar 2000) |
| ascites tumour | <oncology> Tumour that grows in the peritoneal cavity as a suspension of cells. Obviously such cells have lost anchorage dependence and they can easily be isolated and passaged. Hybridomas are sometimes grown as ascites tumours and the ascites fluid can then be used as the crude antiserum. (18 Nov 1997) |
| ascitic tumour | <oncology> A tumour of the abdominal cavity which often causes oedema in that cavity. (09 Oct 1997) |
| Bednar tumour | An uncommon variant of dermatofibrosarcoma protuberans containing heavily pigmented dendritic melanocytes scattered between spindle cells of the tumour. Synonym: Bednar tumour, storiform neurofibroma. (05 Mar 2000) |
| benign nasal tumour | A benign tumour of the posterior nasopharynx that is most common in adolescent boys. Symptoms repeated epistaxis, nasal congestion, nasal discharge and hearing loss. A skull X-ray or a CT scan of the head can confirm the presence of an angiofibroma. Treatment may include the surgical removal of the lesion if it is enlarging or blocking the airway. (27 Sep 1997) |
| benign tumour | <oncology> A nonmalignant clone of neoplastic cells that does not invade locally or spread to other parts of the body (metastasise), having lost growth control but not positional control. Usually surrounded by a fibrous capsule of compressed tissue. (29 Sep 1997) |
| blood tumour | Term sometimes used to denote an aneurysm, haemorrhagic cyst, or haematoma. (05 Mar 2000) |
| bone tumour | <oncology> A general term that includes both malignant growths (cancer) and benign growths in bone. most cancer in bone tissue is secondary to spread (metastasis) from a distant primary cancer (for example prostate cancer). Primary bone cancer (for example osteogenic sarcoma) or cancer that arises from the bone cells, is relatively rare. (27 Sep 1997) |
| borderline tumour | A neoplasm of the ovary, usually arising in young women, composed of complex epithelial hyperplasia without stromas invasion; may recur if incompletely removed surgically, but is clinically less aggressive than carcinoma. Synonym: low malignant potential tumour. (05 Mar 2000) |
