Intracytoplasmic dot-like inclusions as cytopathologically useful findings of ependymoma: Case report of adolescent supratentorial anaplastic ependymoma with clear cell morphology.

ABSTRACT

Pediatric supratentorial ependymomas often have a clear cell morphology and reveal a RELA fusion. When a clear cell neoplasm is intraoperatively diagnosed, intracytoplasmic dot-like inclusions by cytology are a useful cytopathological feature of ependymoma.
