Summary
This study reports a rare congenital ependymoma in a fetus, characterized by typical ependymal rosettes and specific immunohistochemical markers suggesting an ectodermal origin.
Area of Science:
- Neuropathology
- Developmental Biology
- Oncology
Background:
- Congenital central nervous system (CNS) tumors are rare, with ependymomas representing a subset.
- Understanding the cellular origin and differentiation of fetal CNS neoplasms is crucial for diagnosis.
Observation:
- A well-vascularized congenital ependymoma was identified in a 23-week-old fetus.
- The tumor exhibited typical ependymal rosettes and cellular morphology consistent with ependymoma.
Findings:
- Immunohistochemical analysis revealed weak reactivity for neuron-specific enolase and vimentin.
- Strong S-100 protein and cytokeratin antigenicity were observed in some tumor cells.
- Absence of glial fibrillary acidic protein (GFAP) reactivity was noted, atypical for ependymomas.
Implications:
- The immunohistochemical profile suggests a possible ectodermal origin, distinct from typical glial differentiation.
- This case highlights the diverse origins and potential diagnostic challenges of congenital ependymomas.
- Further research into fetal CNS tumor origins is warranted.
