Pineoblastomas in Pediatric Patients: A Single Institutional Experience

Pineoblastomas are rare, malignant pineal parenchymal tumors encountered predominantly in pediatric patients. They distinct from primitive neuroectodermal (PNET) at other sites that they exhibit photosensory differentiation including Flexner–Wintersteiner rosettes and fleu-rettes. Diagnosis can be challenging since share morphologic immunohistochemical fea-tures with embryonal the developing gland. Pineal anlage tumor is a rare variant of pineoblastoma defined by divergent neuroepithelial ectomesenchymal differentia-tion without an endodermal component. To date five published cases be-haved aggressively. We describe case series which includes one patient tu-mor clinical, radiological pathological characteristics pineoblastomas.
