CONTEXT The prevalence of brain tumors in the pediatric population differs from that in the adult population. Similarly, the frequency and location of the different histologic types of brain tumors vary significantly between the pediatric and adult populations. OBJECTIVE To familiarize the pathologist with the pediatric brain tumors encountered during intraoperative consultation and with the ...
Objectives. The B-cell-specific moloney leukemia virus insertion site 1 (the Bmi-1) gene is an important member in the family of polycomb group (PcG) genes that plays an oncogenic role in several types of cancer, but it's expression as a prognostic marker in pediatric brain tumors has not been indicated. Materials and Methods. The Bmi-1 gene expression, clinic pathological and prognostic signif...
: Glomus tumors are rare lesions that can arise anywhere along the spinal axis. Only 12 cases have been reported. We report a case of patient with glomangioma thoracic spine. Following review previous is discussion glomus tumors, including clinical presentation, diagnosis, and treatment. A single, recent arising from extradural space spine described, followed by literature tumors. Including our...
abstract objective: to evaluate and review our experience with pediatric spinal injuries and factors affecting outcome, the authors conducted a retrospective clinical study of 43 cases (32 boys, 11 girls) of pediatric spine injuries treated during four years (january 1999 to december 2003). methods: forty-three children with spinal injuries were studied retrospectively over four years and w...
A heterogeneous population of uncommon neoplasms of the central nervous system (CNS) cause significant morbidity and mortality. To explore their genetic origins, we sequenced the exomes of 12 pleomorphic xanthoastrocytomas (PXA), 17 non-brainstem pediatric glioblastomas (PGBM), 8 intracranial ependymomas (IEP) and 8 spinal cord ependymomas (SCEP). Analysis of the mutational spectra revealed tha...
tumors that originate from the nerve sheath comprise diverse groups -perineuroma, neurofibroma and schwannoma. the epithelioid variant of these tumors is uncommon and mostly seen in malignant counterparts. although this type of morphology is well recognized in peripheral nerve sheath tumors, its presence in the central nerves is rarely reported. very few cases of nerve sheath tumors have been r...
