| 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, gonadal tissue | Neoplasms composed of ovarian or testicular tissue. This concept does not refer to neoplasms located in the ovaries or testes. (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. (12 Dec 1998) |
| neoplasms, multiple primary | Two or more abnormal growths of tissue occurring simultaneously. The neoplasms are histologically different and may be found in the same or different sites. (12 Dec 1998) |
| neoplasms, muscle tissue | Neoplasms composed of muscle tissue: skeletal, cardiac, or smooth. The concept does not refer to neoplasms located in muscles. (12 Dec 1998) |
| neoplasms, nerve tissue | Neoplasms composed of nerve tissue. This concept does not refer to neoplasms located in the nervous system or its component nerves. (12 Dec 1998) |
| neoplasms, neuroepithelial | Neoplasms composed of epithelial cells of the nervous system. This concept does not refer to neoplasms located in the nervous system, nerves, or neural tissue. (12 Dec 1998) |
| neoplasms, posttraumatic | Cancers, tumours, or other neoplasms caused by or resulting from trauma or other non-radiation injuries. (12 Dec 1998) |
| neoplasms, second primary | Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause. (12 Dec 1998) |
| neoplasms, squamous cell | Neoplasms composed of squamous cells of the epithelium. The concept does not refer to neoplasms located in tissue composed of squamous elements. (12 Dec 1998) |
| neoplasms, unknown primary | Metastases in which the tissue of origin is unknown. (12 Dec 1998) |
| neoplasms, vascular tissue | Neoplasms composed of vascular tissue. This concept does not refer to neoplasms located in blood vessels. (12 Dec 1998) |
| meningeal neoplasms | Neoplasms located in any of the meninges, the dura mater, pia mater, or arachnoid. (12 Dec 1998) |
|---|---|
| choroid neoplasms | Tumours of the choroid; most common intraocular tumours are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi). (12 Dec 1998) |
| choroid plexus neoplasms | Neoplasms of the choroid plexus, blood vessels of the pia mater that project into the brain ventricles. (12 Dec 1998) |
| colourectal neoplasms | Cancer of the colon and rectum. The most frequent malignant tumour in the united states. Aetiological factors which increase the risk of colourectal cancer include chronic ulcerative colitis, familial polyposis of the colon, exposure to asbestos, irradiation of the cervix. (12 Dec 1998) |
| colourectal neoplasms, hereditary nonpolyposis | A syndrome characterised by autosomal dominant inheritance, a low mean age (41 years) for occurrence of colon cancer, and a marked increase in the proportion of tumours in the proximal colon. (12 Dec 1998) |
| common bile duct neoplasms | Neoplasms of the common bile duct including vater's ampulla and oddi's sphincter. (12 Dec 1998) |
| pleural neoplasms | Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms. (12 Dec 1998) |
| muscle neoplasms | Neoplasms located in muscle tissue or specific muscles. They are differentiated from neoplasms, muscle tissue which are neoplasms composed of skeletal, cardiac, or smooth muscle tissue, such as myosarcoma or leiomyoma. (12 Dec 1998) |
| cranial nerve neoplasms | Neoplasms of any of the cranial nerves. (12 Dec 1998) |
| haematologic neoplasms | Neoplasms located in the blood and blood-forming tissue (the bone marrow and lymphatic tissue). The commonest forms are the various types of leukaemia, of lymphoma, and of the progressive, life-threatening forms of the myelodysplastic syndromes. (12 Dec 1998) |
| head and neck neoplasms | Neoplasms of the head and neck. (12 Dec 1998) |
| skull base neoplasms | Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (skull neoplasms). (12 Dec 1998) |
| skull neoplasms | Neoplasms of the bony part of the skull. (12 Dec 1998) |
| hypothalamic neoplasms | Neoplasms located in the hypothalamus including the anterior, medial, and posterior portions. (12 Dec 1998) |
| soft tissue neoplasms | Neoplasms of whatever cell type or origin, occurring in the extraskeletal connective tissue framework of the body including the organs of locomotion and their various component structures, such as nerves, blood vessels, lymphatics, etc. (12 Dec 1998) |
