Comparison of the incidence of the various types of spinal tumors in infancy and childhood to other age groups reveals significant differences, similar to the brain tumors. Compared with intramedullary tumors in adult patients (16%), the incidence of intramedul1ary bIastomas is higher in children and young adults (1-16 years) (25%). Intramedullary tumors become prevalently manifest as gliomas (...

Abstract Background and Purpose Glioblastoma is the most poorest prognosis tumor of all carcinomas. Various factors contribute to deterioration for glioblastoma such as age, KPS, surgical removal level. The important poor are that half patients with have a KPS ≤ 70 at start treatment because progresses rapidly. There been no comprehensive reports on trends in visits time initiation glioblastoma...

abstract salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. most benign tumors occur in the parotid gland. pleomorphic adenoma is the most common type. basal cell adenoma is a subtype of the monomorphic adenoma with rare occurrence. proper diagnosis and clinical evaluation by the use of radiography can lead the physician to t...

background and objective: approximately 45% of benign peripheral nerve sheath tumors (pnst) occur in head and neck regions. malignant peripheral nerve sheath tumors (mpnst) are less common and only 8-15% of these tumors occur in head and neck region. in this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family hist...

Human glioma, arising from glial cells of the central nervous system, accounts for almost 30%of all brain tumours , neoplasms with a poor prognosis and high mortality rates worldwide. In the present study we assessed tissue architectural modifications associated with macrophage lineage cells, controversial major immune effector cells within the brain, in human glioma tissue samples from eastern...
