| sertoli cell tumour | A rare benign tumour of the testis that histologically resembles the foetal testis. There are three varieties: diffuse stromal, mixed (stromal and epithelial), and tubular (epithelial). Sertoli cells in the epithelial elements may produce oestrogen and cause feminization. (12 Dec 1998) |

| sertoli-leydig cell tumour | An ovarian tumour usually of low-grade malignancy occurring most frequently in the third and fourth decades, with 75% seen in women under 40. It is rare, representing less than .02% of ovarian cancers. The tumour typically produces androgens with virilization being noted in 70-85% of the patients. (holland et al., cancer medicine, 3d ed, p1684) (12 Dec 1998) |
| 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) |
| 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) |
| sugar tumour | A benign clear cell tumour of the lung containing abundant glycogen. (05 Mar 2000) |
| debulking of tumour | <surgery> The surgical removal of as much of a tumour as is possible, although the surgeon is unable to remove the whole thing. (09 Oct 1997) |
