Role of immunohistochemistry in the identification of supratentorial C11ORF95-RELA fused ependymoma in routine neuropathology
Ependymomas (EPs) are tumors of the brain and spinal cord constituting ∼10% of the childhood central nervous system neoplasms and about 30% in children aged <3 years. Their anatomic distribution varies according to the age, with those arising in the supratentorial (ST) compartment, spinal cord being more common in older children and adults, and those at the infratentorial location are more common and occurring more frequently in infants and children.
