title: Recurrent anaplastic ependymoma with an abnormal karyotype and c-myc proto-oncogene overexpression.
abstract: Cytogenetic analysis on a supratentorial, recurrent, anaplastic ependymoma from a 29-year-old female disclosed the presence of an abnormal clone with the karyotype 46,XX,der(8)t(8;11)(q24;p11),-11,add(?)t(?;11)(?;q13). By the Northern hybridization assay and immunohistochemical staining, tumor cells revealed overexpression of c-myc proto-oncogene, although no evidence of amplification or structural rearrangement of this gene was found.
