This presentation analyses the histological types, relative incidences, age, sex and anatomical distributions of one hundred and seventy-nine biopsy proven tumors of the spinal canal from a general hospital in Iran. Particular attention is paid to differences in the relative incidence of these tumors compared with that in various published reports and the statistics from several eastern co...

Fifteen pediatric (age under 16) cases of oligodendroglioma (ODG) were surgically proven from January 1985 to April 1992 at the Division of Pediatric Neurosurgery, Seoul National University Children's Hospital. To observe the proportion of ODG's in primary intracranial tumors, the location of ODG's and the prognostic significance of the histological grading of ODG's in childhood, the 15 cases o...

We inspected on about 110 patients of spinal tumors in the neurosurgical department of Loghman-e­Hakim Medical Center. According with our inspectation, we have considered the factors such as age, sex, pathology, clinical signs, radiology, kind of operation and…. cases were up to 16 years ( 15 % ) and the  17 ‏ others were adult. 62 (56%) were male and 38 (44%) were female. The most privalent ...

background: tumors of the central nervous system (cns) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of cns. objectives: determining the relative frequency of different types of cns tumors in different ages, sex and cns anatomical locations. materials and methods: this retrospective study was performed using pathological repor...

Myxopapillary ependymoma (MEPN) generally can be cured by gross total surgical resection and usually manifest a favorable prognosis. However, surgery is less curative in tumors that are large, multifocal or extend outside the thecal sac. Late recurrences may occur, particularly in pediatric patients. The role of adjuvant therapy is unclear in the clinical management of recurrent tumors. Clinica...

High-grade gliomas of the spinal cord represent a rare entity in children. Their biology, behavior, and controversial treatment options have been discussed in a few pediatric cases. These tumors are associated with severe disability and poor prognosis. We report a case of a 4-year-old child diagnosed with an isolated glioblastoma multiforme of the conus medullaris. The patient underwent subtota...

AIM: The authors discuss the current management of intramedullary spinal cord tumors in children and young adults. Intramedullary spinal cord tumors of the pediatric population are rare and comprise only a small percentage of all central nervous system neoplasms. There has been much controversy with the surgical management of these tumors. METHODS: The majority of these neoplasms are histologic...

Glioneuronal neoplasms are rare tumors. Recently, an unusual glioneuronal tumor histologically showing neuropil-like islands has been described. Here, we present such a tumor originating from spinal cord of a 14-year-old girl, who has scoliosis and urinary incontinence. Microscopically, the glial component was chiefly fibrillary astrocytic, punctuated by neuropil-like islands. Immunohistochemic...

Background: Understanding the differences in genetics of malignancies is crucial for therapeutic decisions. This systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. Material and Methods: We performed a systematic review of the literature published on genetics of pediatrics bone tumors, using PubMed, Google scholar,...
