Five brain tumors in infancy were studied histopathologically. Though four of them could be included in primitive neuroectodermal tumor, histopathological findings were diverse. The diagnoses were medulloblastoma, cerebellar neuroblastoma, pineoblastoma, ependymoblastoma and ependymoma. While conventional stain for microscopy exhibited their specific findings, immunohistochemical and electron microscopical studies revealed morphological findings related functional structures of the tumor cells. These methodology is mandatory in order to elucidate cytogenesis and differentiation of infantile brain tumors.
