| dif-PIPE | diffuse persistent interstitial pulmonary emphysema |
| mammary tumour virus of mice | 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) |

| ranine tumour | <medicine> A cyst formed under the tongue by obstruction of the duct of the submaxillary gland. Origin: L, a little frog, a little swelling on the tongue of cattle, dim. Of rana a frog. Source: Websters Dictionary (01 Mar 1998) |
| paraffin tumour | A tumefaction, usually a granuloma, caused by the prosthetic or therapeutic injection of paraffin into the tissues; sometimes used with reference to similar lesions resulting from the injection of any oil, wax, or the like. See: lipogranuloma. Synonym: paraffin tumour. (05 Mar 2000) |
| Rathke's pouch tumour | <oncology, tumour> A form of primary brain tumour which develops in the pituitary gland. These tumours often secrete increased quantities of pituitary hormones (for example growth hormone) which can result in conditions such as gigantism and acromegaly. They are often benign and rare and comprise less than 5% of childhood brain tumours. Other symptoms include vision changes, headache and weight gain. Treatment often includes a combination of surgery and radiation therapy. (27 Sep 1997) |
| genes, suppressor, tumour | Genes that inhibit expression of the tumourigenic phenotype. They are normally involved in holding cellular growth in check. When tumour suppressor genes are inactivated or lost, a barrier to normal proliferation is removed and deregulated growth is possible. (12 Dec 1998) |
| genes, wilms' tumour | Tumour suppressor genes located in the 11p13 region on the short arm of human chromosome 11. The absence of these genes is associated with the formation of wilms' tumour. (12 Dec 1998) |
| receptors, tumour necrosis factor | Cell surface receptors that bind tumour necrosis factor and trigger changes which influence the behaviour of cells. The two recognised tumour necrosis factor receptors are designated alpha and beta receptors. Both receptors bind both alpha and beta tumour necrosis factors with high affinity, and both are members of the nerve growth factor receptor family. (12 Dec 1998) |
| Recklinghausen's 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) |
| carotid body tumour | An invariably benign, encapsulated, firm round mass at the bifurcation of the common carotid artery, with nests of large polyhedral cells in alveolar or organoid arrangement. It is usually asymptomatic but large masses may encroach upon the parapharyngeal space and produce dysphagia, pain, and cranial nerve palsies. (12 Dec 1998) |
| villous tumour | <tumour> A papilloma composed of slender, finger-like excrescences occurring in the bladder or large intestine, or from the choroid plexus of the cerebral ventricles; villous papilloma's of the colon are usually sessile and frequently become malignant. Synonym: villous tumour. (05 Mar 2000) |
| Gleason's tumour grade | A classification of adenocarcinoma of the prostate by evaluation of the pattern of glandular differentiation; the tumour grade, know as Gleason's score, is the sum of the dominant and secondary patterns, each numbered on a scale of 1 to 5. (05 Mar 2000) |
| glomus jugulare tumour | A paraganglioma involving the glomus jugulare, a microscopic collection of chemoreceptor tissue in the adventitia of the bulb of the jugular vein. It may cause paralysis of the vocal cords, attacks of dizziness, blackouts, and nystagmus. It is not resectable but radiation therapy is effective. It regresses slowly, but permanent control is regularly achieved. (12 Dec 1998) |
| glomus tumour | A blue-red, extremely painful paraganglioma involving a glomeriform arteriovenous anastomosis (glomus body), which may be found anywhere in the skin, most often in the distal portion of the fingers and toes, especially beneath the nail. They may also occur in the stomach and nasal cavity. It is composed of specialised pericytes (sometimes termed glomus cells), usually in single encapsulated nodular masses which may be several millimeters in diameter. When located in the usual subungual site, the abundant innervation makes the tumour exquisitely painful; when located elsewhere, the glomus tumour is painless. (12 Dec 1998) |
| pearl tumour | An obsolete term for cholesteatoma. (05 Mar 2000) |
| cellular tumour | A tumour composed mainly of closely packed cells. (05 Mar 2000) |
