| 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) |

| endometrial neoplasms | The most common invasive gynecologic malignancy in the united states, typically in postmenopausal women. The neoplasm originates on the endometrial mucosa and may be focal or diffuse. It may progress to invasion of the myometrium. The commonest histologic type is adenocarcinoma but adenoacanthoma, adenosquamous carcinoma, epidermoid carcinoma, and other histological types of cancer are possible. (12 Dec 1998) |
| epidural neoplasms | Neoplasms located in the epidural space, at or above the dura mater of the spinal cord. (12 Dec 1998) |
| trophoblastic neoplasms | Trophoblastic growth, which may be gestational or nongestational in origin. Trophoblastic neoplasia resulting from pregnancy is often described as gestational trophoblastic disease to distinguish it from germ cell tumours which frequently show trophoblastic elements, and from the trophoblastic differentiation which sometimes occurs in a wide variety of epithelial cancers. Gestational trophoblastic growth has several forms, including hydatidiform mole and choriocarcinoma. (12 Dec 1998) |
