| histoid tumour | Old term for a tumour composed of a single type of differentiated tissue. (05 Mar 2000) |
|---|---|
| secondary tumour | <oncology> A tumour that develops as a result of metastasis or spreads beyond the original cancer. (09 Oct 1997) |
| homologous tumour | <oncology> Any tumour which is composed of the same tissue as that in which it arose. (09 Oct 1997) |
| sex cord-stromal tumour | A malignant neoplasm of the ovary or testis. These tumours differentiate toward sex cords (in embryonic gonads) in the form of female (i.e., granulosa and theca) cells, male (i.e., sertoli and leydig) cells, or indifferent elements. In the ovary, sex cord-stromal tumours comprise 5% of all ovarian neoplasms. In the testes, leydig and sertoli cell tumours comprise about 5% of all testicular neoplasms, 10% of which behave in a malignant fashion. (12 Dec 1998) |
| hylic tumour | <tumour> A neoplasm of pulp tissue, resulting from proliferation of elements derived from the embryonic pulp of epiblastic origin. Synonym: hylic tumour. Origin: G. Hyle, stuff, crude matter, + -oma, tumour (05 Mar 2000) |
| smooth muscle tumour | A tumour composed of smooth muscle tissue, as opposed to leiomyoma, a tumour derived from smooth muscle. (12 Dec 1998) |
| solid tumour | A cancer that originates in organ or tissue other than bone marrow or the lymph system. (16 Dec 1997) |
| solitary fibrous tumour | A benign tumour of fibrous tissue which usually arises in the pleural space on other sites. Synonym: benign mesothelioma. (05 Mar 2000) |
| spinal cord tumour | A spinal cord tumour is a aggregate if cells that form a mass that can compress the spinal cord. Spinal cord tumours may arise from local structures (for example meninges) or from a cancer from a distant site (i.e. Metastasis). Regardless of the aetiology, all spinal cord tumours cause symptoms from compression on the spinal cord, surrounding nerve roots or blood vessels that supply the cord. Symptoms are variable with the extent and the level of the spinal cord tumour. Common symptoms include back pain that may radiate, numbness and tingling to the lower extremities, muscle weakness in the legs, difficulty walking and loss of bowel and bladder control (incontinence).

| squamous odontogenic tumour | A benign epithelial odontogenic tumour thought to arise from the epithelial cell rests of Malassez; appears clinically as a radiolucent lesion closely associated with the tooth root and histologically as islands of squamous epithelium enclosed by a peripheral layer of flattened cells. (05 Mar 2000) |
| Nelson tumour | A pituitary tumour causing the symptoms of Nelson syndrome. (05 Mar 2000) |
| neuroectodermal tumour, melanotic | A benign, rapidly growing, deeply pigmented tumour of the jaw and occasionally of other sites, consisting of an infiltrating mass of cells arranged in an alveolar pattern, and occurring almost exclusively in infants. Its source of origin is in dispute, the various theories giving rise to its several names. (12 Dec 1998) |
| neuroectodermal tumour, peripheral | A heterogeneous group of malignant neoplasms arising in either supportive structures or neuronal tissue. They occur in adolescents and young adults. This tumour shares a number of characteristics with ewing's sarcoma: it is highly cellular and consists of a monotonous pattern of primitive-appearing round cells. The chest wall is the most common site but the trunk, abdomen, and pelvis are other primary sites. (12 Dec 1998) |
| neuroectodermal tumour, primitive | A malignant brain tumour sharing common features and biologic properties with medulloblastoma. Some pathologists and clinicians use the terms interchangeably: they both can disseminate throughout the nervous system and, in some cases, systemically. most lesions arise from the posterior fossa in children under five years of age. The tumour often produces hydrocephalus and symptoms of increased intracranial pressure. Papilledema is often present. (12 Dec 1998) |
