Insights
Subcutaneous ependymomas in the natal cleft can be successfully resected without coccyx removal, showing no recurrence. These tumors may arise from ectopic ependymal rests, not connected to the spinal cord.
Area of Science:
- Neuroscience
- Pediatric Surgery
- Developmental Biology
Background:
- Ependymomas are tumors arising from ependymal cells, typically found in the central nervous system.
- Subcutaneous ependymomas in the natal cleft are rare pediatric tumors.
- The origin and relationship of these tumors to the spinal cord remain areas of investigation.
Observation:
- A 4-year-old girl underwent resection of a 2 cm subcutaneous ependymoma from the natal cleft.
- The coccyx was preserved during surgery, and no recurrence was observed over 14 years.
- Histological examination of the post-coccygeal region in 15 infants revealed subcutaneous ependymal islands.
Findings:
- Ectopic ependymal tissue was found in the subcutaneous region of the post-coccygeal area in infants.
- These ependymal islands were not connected to the cauda equina.
- Infants with post-anal dimples showed a higher incidence of these ectopic ependymal rests.
Implications:
- Subcutaneous ependymomas in the natal cleft may originate from these unconnected, ectopic ependymal rests.
- Coccygectomy may not be necessary for treating these specific types of ependymomas, potentially reducing surgical morbidity.
- Further research into the developmental origins of these ectopic tissues could improve understanding and management of natal cleft tumors.
Abstract:
A 2 cm subcutaneous ependymoma was resected from the natal cleft of a 4-yr-old girl. The coccyx was not removed and there has been no recurrence in 14 years. A study of the post-coccygeal region in 15 control infants revealed subcutaneous islands of ependyma, unconnected with the cauda equina, in 4/4 infants with post-anal dimples and in 6/11 infants with no external post-coccygeal anomaly.
