Ganglioneuroblastoma is a variant of neuroblastoma that is surrounded by ganglion cells. ... Nodular ganglioneuroblastoma can be divided by prognosis. [2]
Micrograph of a ganglioneuroma with the characteristic ganglion cells. H&E stain. Pathologically, ganglioneuromas are composed of ganglion cells, Schwann cells and fibrous tissue. [5] Ganglioneuromas are solid, firm tumours that typically are white when seen with the naked eye. [citation needed]
Histologically, ganglioglioma is composed of both neoplastic glial and ganglion cells which are disorganized, variably cellular, and non-infiltrative. Occasionally, it may be challenging to differentiate ganglion cell tumors from an infiltrating glioma with entrapped neurons.
Neuroblastoma often spreads to other parts of the body before any symptoms are apparent, and 50 to 60% of all neuroblastoma cases present with metastases. [8] The most common location for neuroblastoma to originate (i.e., the primary tumor) is in the adrenal glands. This occurs in 40% of localized tumors and in 60% of cases of widespread disease.
The median age for the diagnosis of neuroblastoma is 22 months, being rare in adolescence and adulthood but showing poor prognosis when it does present in those age groups. The degree of differentiation of neuroblastoma is correlated to the prognosis, with a wide variety of outcomes (from tumor regression to recurrence and mortality).
