Ganglioneuroma is a benign neuroblasic tumour. It is also known as ganglioma.[1]
It should not to be confused with ganglioglioma.
General
- May be retroperitoneal.
- Occasionally found in the GI tract - may form colonic polyp.
- Multiple ganglioneuromas may be due to multiple endocrine neoplasia IIb.
Classification:
- In a grouping known as neuroblastic tumours which includes:[2]
- Ganglioneuroma (benign).
- Ganglioneuroblastoma (intermediate).
- Neuroblastoma (aggressive).
Gross
- Solid.
- White.
- Firm.
- Well-circumscribed.
- May be nodular.
