Overview
Classification
According to International Neuroblastoma Pathology Classification (INPC), ganglioneuroma may be classified into two subtypes/groups: Ganglioneuroma-maturing and ganglioneuroma-mature.[1]
Pathophysiology
On gross pathology, ganglioneuromas are characterized by solid, white, firm, well-circumscribed, and nodular tumors. On microscopic histopathological analysis, ganglioneuromas are characterized by spindle-shaped cells with cell borders in a fibrillar matrix containing ganglion cells with large round nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm.[2] Genes involved in the pathogenesis of ganglioneuroma include MYCN oncogene and chromosome 1p36.
Causes
There are no established causes for ganglioneuroma.[3]
Differentiating brain tumors from other diseases
Ganglioglioma must be differentiated from neuroblastoma, ganglioneuroblastoma, spinal schwannoma, spinal neurofibroma, adrenal adenoma, adrenal carcinoma, and pheochromocytoma.[3][4]
Epidemiology and Demographics
The incidence of ganglioneuroma is approximately 1 per 100,000 children in the United States.[4] Ganglioneuroma is a rare disease that tends to affect children and young adults.[3] Females are more commonly affected with ganglioneuroma than males.[4] There is no racial predilection to ganglioneuroma.
Risk factors
There are no established risk factors for ganglioneuroma.[3]
Screening
Screening for ganglioneuroma is not recommended.[5]
Natural History, Complications and Prognosis
Common complications of ganglioneuroma include paralysis, metastases, and local recurrence.[6] The prognosis of ganglioneuroma is excellent with treatment.[3]
Diagnosis
Staging
According to the International Neuroblastoma Staging System (INSS), there are six stages of ganglioneuroma based on clinical, radiologic, and surgical features.[4]
History and Symptoms
Symptoms of ganglioneuroma include dyspnea, chest pain, abdominal pain, bloating, pain and numbness in limbs, paresis, diarrhea, diaphoresis, and hirsuitism.[3]
