| gemistocytic astrocyte | <cell biology> A round to oval astrocyte cell with abundant cytoplasm containing glial filaments and an eccentric nucleus; may contain two nuclei in the cell hypertrophy of astrocytes.

| gemistocytic cell | <cell biology> A round to oval astrocyte cell with abundant cytoplasm containing glial filaments and an eccentric nucleus; may contain two nuclei in the cell hypertrophy of astrocytes. Synonym: gemistocyte, gemistocytic cell, reactive astrocyte, reactive cell. (05 Mar 2000) |
| gemistocytic reaction | <cell biology> A reaction to injury resulting in the proliferation of reactive, protoplastic, or gemistocytic astrocytes. (05 Mar 2000) |
| anaplastic astrocytoma | <tumour> Intermediate grade astrocytoma characterised by increased cellularity, nuclear pleomorphism, mitoses, and variable vascular endothelial proliferation. (05 Mar 2000) |
| astrocytoma | <oncology, tumour> A neuro ectodermal tumour (glioma) arising from astrocytes. Probably the commonest glioma, it has a tendency to become anaplastic. (18 Nov 1997) |
| giant cell astrocytoma | <radiology> Malignant transformation from hamartoma (tuber) of tuberous sclerosis, enhances (unlike benign lesions), arises only about foramen of Monro, not really an astrocytoma, it's a giant-cell tumour (12 Dec 1998) |
| cerebellar astrocytoma | <oncology, tumour> This primary brain tumour of the cerebellum accounts for 10 to 30% of brain tumours in children. The are usually slow growing and benign. Symptoms include gait problems, clumsiness, headache and vomiting. Treatment often involves a combination of surgery, radiation therapy and chemotherapy. (27 Sep 1997) |
| grade I astrocytoma | <tumour> Solid or cystic astrocytoma of high differentiation or low grade. (05 Mar 2000) |
| grade II astrocytoma | <tumour> Astrocytoma of intermediate grade. (05 Mar 2000) |
| grade III astrocytoma | <tumour> Astrocytoma of intermediate grade. See: glioblastoma multiforme. (05 Mar 2000) |
| grade IV astrocytoma | <oncology, tumour> A malignant brain tumour that accounts for 75% of glial tumours (arising from glial cells in the brain). Treatment is difficult and consists of a combination of radiation therapy and surgery. (17 Dec 1997) |
| piloid astrocytoma | <tumour> A slowly growing astrocytoma composed histologically of elongated fibrous astrocytes; often located in the optic chiasm or hypothalamus. Synonym: piloid astrocytoma. (05 Mar 2000) |
| plocytic astrocytoma | <tumour> A slowly growing astrocytoma composed histologically of elongated fibrous astrocytes; often located in the optic chiasm or hypothalamus. Synonym: piloid astrocytoma. (05 Mar 2000) |
| protoplasmic astrocytoma | <tumour> A neoplasm composed primarily of protoplasmic-type astrocytes. (05 Mar 2000) |
| subependymal giant cell astrocytoma | <tumour> A rare astrocytoma, frequently located in the wall of the lateral ventricle, comprised of large glial cells with abundant eosinophilic cytoplasm and intermixed elongated astrocytes, associated with tuberous sclerosis. (05 Mar 2000) |
