| brenner tumour | A tumour of the ovary whose structure consists of groups of epithelial cells lying in a fibrous connective tissue stroma. Brenner tumours are uncommon, representing less than 1% of all ovarian neoplasms. Malignant brenner tumours are unilateral. Brenner tumours are ordinarily found incidentally in ovaries removed for other reasons, especially in postmenopausal women. (12 Dec 1998) |

| Brooke's tumour | <tumour> Multiple small benign nodules, occurring mostly on the skin of the face, derived from basal cells of hair follicles enclosing small keratin cysts; frequent autosomal dominant inheritance. Synonym: acanthoma adenoides cysticum, Brooke's tumour, epithelioma adenoides cysticum, hereditary multiple trichoepithelioma. Origin: tricho-+ epithelioma (05 Mar 2000) |
| brown tumour | A mass of fibrous tissue containing haemosiderin-pigmented macrophages and multinucleated giant cells, replacing and expanding part of a bone in primary hyperparathyroidism. (05 Mar 2000) |
| Buschke-Lowenstein tumour | A large type of condyloma acuminatum found in the anus, vulva, or preputial sac of the penis of middle-aged, uncircumcised men; it tends to extend deeply and recur. Synonym: Buschke-Lowenstein tumour. (05 Mar 2000) |
| calcifying epithelial odontogenic 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) |
| carcinoid tumour | A tumour which secretes excessive amounts of the hormone serotonin. The clinical result is carcinoid syndrome. These tumours may grow anywhere in the gastrointestinal tract (and in the lungs) with approximately 90% in the appendix. The remainder occur in the ileum, stomach, colon or rectum. (27 Sep 1997) |
| carcinoma, ehrlich tumour | A transplantable, poorly differentiated malignant tumour which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms. (12 Dec 1998) |
| pancoast tumour | <oncology, tumour> Tumour originating from the superior sulcus of the lung that invades all or a portion of the brachial plexus. (16 Dec 1997) |
| malignant giant cell tumour | A type of bone tumour. (12 Dec 1998) |
| malignant mixed mullerian tumour | A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. Synonym: malignant mixed mullerian tumour. (05 Mar 2000) |
| malignant tumour | A mass of cancer cells. These cells have uncontrolled growth and will invade surrounding tissues and spread to distant sites of the body, setting up new cancer sites, a process called metastasis. (09 Oct 1997) |
| papillary tumour | A tumour shaped like a small mushroom with its stem attached to the inner lining of the bladder. (12 Dec 1998) |
| mammary tumour virus | <organism, virology> Retrovirus that induces mammary carcinoma in mice. Isolated from highly inbred strains that had very high incidence of the tumours, after the discovery that the disease was transmitted by nursing mothers in milk. Endogenous provirus present in germ line of all inbred mice. Transcription of the provirus is regulated by a viral promoter that increases transcription in response to glucocorticoid hormones. May transform by proviral insertion activating the cellular int 1 oncogene (18 Nov 1997) |
| mammary tumour viruses, mouse | The type species of mammalian type b retroviruses (retroviruses type b, mammalian) commonly latent in mice. It causes mammary adenocarcinoma when in a genetically susceptible strain of mice and when the appropriate hormonal influences operate. (12 Dec 1998) |
| 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) |
