Overview
Pathophysiology
Genetics
Development of ganglioneuroma is the result of multiple genetic mutations. Genes involved in the pathogenesis of ganglioneuroma include MYCN oncogene and chromosome 1p36.
Associated Conditions
- Multiple endocrine neoplasia type IIb: particularly with mucosal ganglioneuromas.[1]
- Turner syndrome
- Neurofibromatosis type 1
Gross Pathology
- Ganglioneuromas are solid, firm tumors that are typically white when seen with the naked eye
- Gangliocytoma is commonly located in the following regions:[1]
- Posterior paraspinal mediastinum (most common)
- Adrenal gland
- Paraspinal retroperitoneum
- Neck
Microscopic Pathology
- Ganglioneuromas are derived from the primordial neural crest cells, which are undifferentiated cells of the sympathetic nervous system.
- Ganglioneuromas are fully differentiated neuronal tumors that do not contain immature elements.
- They are composed of ganglion cells, schwann cells and fibrous tissue.
- Histopathology consists of spindled cells, with cell borders in a fibrillar matrix which contain ganglion cells, with large round nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm. No atypia or mitotic activity was evident. The ganglion cells stained positive for S-100 protein.[2]
