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...

pediatric cervicofacial actinomycosis is a rare occurrence consequent to dental infections and manipulations or maxillofacial trauma. the clinical presentation ranges from multiple draining sinuses to swellings resembling tumors and cysts. the present unusual case had congenital dermoid cyst of mid upper lip with actinomyces israelii infection identified on microscopy, culture, and histopatholo...

Background : Till date there is no published multi-institutional data regarding the epidemiological profile of pediatric brain tumors in India. Aim : The present retrospective study analyses the histological spectrum of pediatric age group brain tumors in seven tertiary care hospitals in India. Material and Methods : Data regarding frequencies of various primary brain tumors (diagnosed accordin...

BACKGROUND The aim of this study was to determine the most frequently presenting tumors exclusive to the head and neck within the pediatric population, and to identify racial disparities within the existing incidence rates. MATERIAL/METHODS The population-based Surveillance, Epidemiology, and End Results (SEER) registry was utilized to identify the frequency and incidence rates of various tum...

BACKGROUND Discrimination between benign and malignant tumors is a challenging process in pediatric adrenocortical tumors. New insights in the metabolic profile of pediatric adrenocortical tumors may contribute to this distinction, predict prognosis, as well as identify new molecular targets for therapy. The aim of this work is to characterize the expression of the metabolism-related proteins M...

OBJECTIVE Tumors of the central nervous system are now thought to be the most common form of childhood malignancies. Previous studies suggested that delays might exist between symptom onset and the diagnosis of pediatric brain tumors. In the Maritime Provinces of Canada (New Brunswick, Nova Scotia, and Prince Edward Island), there are only two pediatric neurosurgical centers; therefore, the Mar...
