Ependymoma with Intraorbital Extracerebral Recurrence: Case Report

Brazilian Neurosurgery, 2019
Ependymomas are rare neuroepithelial tumors that originate from a type of glial cell called ependymal cell. In general, they correspond to ∼ 1.2 to 7.8% of all intracranial neoplasms, and to ∼ 2 to 6% of all gliomas. Although it corresponds only to ∼2 to

Clinical Implication of Targeting of Cancer Stem Cells [PDF]

, 2012
The existence of cancer stem cells (CSCs) is receiving increasing interest particularly due to its potential ability to enter clinical routine. Rapid advances in the CSC field have provided evidence for the development of more reliable anticancer ...

Pediatric spinal ependymomas: Long‐term surgical outcomes in a cohort of 61 cases

Pediatric Investigation, EarlyView.
Spinal ependymomas are rare in children, with limited long‐term outcome data. In this retrospective study of 61 pediatric patients undergoing surgical resection, gross total resection was achieved in 62.3% and was associated with favorable functional improvement. Recurrence was observed in 31.1% of cases.

Neoplasm of mixed mesenchymal and neuroepithelial origin: liposarcomatous meningioma combined with gliomas [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 1973
A case is reported of an intracranial neoplasm of mixed mesenchymal and neuroepithelial (glial) origin occurring in the parieto-parasagittal region of the brain of a 19 year old man. A meningioma with liposarcomatous and psammomatous components comprised the mesenchymal part of the combined tumour.

[11C]-Methionine PET: dysembryoplastic neuroepithelial tumours compared with other epileptogenic brain neoplasms [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2005
Brain tumours responsible for longstanding partial epilepsy are characterised by a high prevalence of dysembryoplastic neuroepithelial tumour (DNT), whose natural evolution is much more benign than that of gliomas. The preoperative diagnosis of DNT, which is not yet feasible on the basis of available clinical and imaging data, would help optimise the ...

Malignant craniopharyngiomas: Institutional experience and literature review

Brain Pathology, EarlyView.
We report the second case of malignant craniopharyngioma with BAP1 and TP53 mutations. A literature review identified 44 cases of malignant craniopharyngiomas with a median overall survival of 6 months. Eighteen (41%) occurred in patients without any history of radiation, suggesting that mechanisms other than radiation have contributed to their ...

Different immunohistochemical levels of Hsp60 and Hsp70 in a subset of brain tumors and putative role of Hsp60 in neuroepithelial tumorigenesis

European Journal of Histochemistry, 2013
In this work we analysed, by immunohistochemistry, a series of brain tumors to detect the levels and cellular distribution of Hsp60 and Hsp70. We found that Hsp60 levels were significantly higher than those of Hsp70 in neuroepithelial tumors, while ...

Immunohistochemistry as a tool for identifying EGFR amplification in CNS tumors

Brain Pathology, EarlyView.
EGFR gene amplification constitutes a diagnostic hallmark for glioblastoma, IDH‐wildtype (GB, IDH‐WT). Herein, we demonstrated that EGFR IHC is a highly specific and sensitive biomarker for identifying EGFR amplification and should be part of the neuropathologist's routine panel of antibodies.
