| 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) |
| sublingual gland neoplasms | Neoplasms of the sublingual glands. (12 Dec 1998) |
| supratentorial neoplasms | Neoplasms located above the tentorium cerebelli, a fold of dura mater separating the cerebellum from the cerebral cortex occipital and temporal lobes. (12 Dec 1998) |
| ileal neoplasms | Neoplasms of the ileum including the ileocaecal valve. (12 Dec 1998) |
| infratentorial neoplasms | Intracranial tumours originating in the infratentorial region and occurring in both children and adults. Histological diagnoses include teratoma, medulloblastoma, glioblastoma, astrocytoma, ependymoma, craniopharyngioma, choroid plexus papilloma, and undetermined types. Therapeutic treatments include tumour resection, ventriculoperitoneal shunt, subdural peritoneal shunt, ventricular drainage, radiotherapy, and chemotherapy. (12 Dec 1998) |
| iris neoplasms | Tumours of the iris characterised by increased pigmentation of melanocytes. Iris nevi are composed of proliferated melanocytes and are associated with neurofibromatosis and malignant melanoma of the choroid and ciliary body. Malignant melanoma of the iris often originates from preexisting nevi. (12 Dec 1998) |
| orbital neoplasms | Neoplasms of the bony orbit and contents except the eyeball. (12 Dec 1998) |
| otorhinolaryngologic neoplasms | The general concept of orl neoplasms or those for which no specific heading exists. (12 Dec 1998) |
