| hypothalamic neoplasms | Neoplasms located in the hypothalamus including the anterior, medial, and posterior portions. (12 Dec 1998) |
|---|---|
| spinal cord neoplasms | Neoplasms located in the spinal cord. They include neoplasms in the inner core or the outer layer of the cord, but not those in the protective membranes, or meninges ( = meningeal neoplasms). (12 Dec 1998) |
| neoplasms | New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms. (12 Dec 1998) |
| neoplasms, adnexal and skin appendage | Neoplasms composed of sebaceous or sweat gland tissue or tissue of other skin appendages. The concept does not refer to neoplasms located in the sebaceous or sweat glands or in the other skin appendages. (12 Dec 1998) |
| neoplasms, basal cell | Neoplasms composed of cells from the deepest layer of the epidermis. The concept does not refer to neoplasms located in the stratum basale. (12 Dec 1998) |
| neoplasms by histologic type | A collective term for the various histological types of neoplasms. It is more likely to be used by searchers than by indexers and catalogers. (12 Dec 1998) |
| neoplasms by site | A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as brain neoplasms, duodenal neoplasms, liver neoplasms, etc. (12 Dec 1998) |
| neoplasms, complex and mixed | Neoplasms composed of more than one type of neoplastic tissue. (12 Dec 1998) |
| neoplasms, cystic, mucinous, and serous | Neoplasms containing cyst-like formations or producing mucin or serum. (12 Dec 1998) |
| neoplasms, ductal, lobular, and medullary | Neoplasms, usually carcinoma, located within the centre of an organ or within small lobes, and in the case of the breast, intraductally. The emphasis of the name is on the location of the neoplastic tissue rather than on its histological type. most cancers of this type are located in the breast. (12 Dec 1998) |
| neoplasms, fibroepithelial | Neoplasms composed of fibrous and epithelial tissue. The concept does not refer to neoplasms located in fibrous tissue or epithelium. (12 Dec 1998) |
| neoplasms, germ cell and embryonal | Neoplasms composed of primordial germ cells of embryonic gonads or of elements of the germ layers of the embryo. The concept does not refer to neoplasms located in the gonads or present in an embryo or foetus. (12 Dec 1998) |
| neoplasms, glandular and epithelial | Neoplasms composed of glandular tissue, an aggregation of epithelial cells that elaborate secretions, and of any type of epithelium itself. The concept does not refer to neoplasms located in the various glands or in epithelial tissue. (12 Dec 1998) |
| neoplasms, hormone-dependent | Certain tumours that 1) arise in organs that are normally dependent on specific hormones and 2) are stimulated or caused to regress by manipulation of the endocrine environment. (12 Dec 1998) |
| neoplasms, mesothelial | Neoplasms composed of tissue of the mesothelium, the layer of flat cells, derived from the mesoderm, which lines the body cavity of the embryo. In the adult it forms the simple squamous epithelium which covers all true serous membranes (peritoneum, pericardium, pleura). The concept does not refer to neoplasms located in these organs.
