ganglioneuroma

 [gang″gle-o-nu-ro´mah]
a benign neoplasm composed of nerve fibers and mature ganglion cells; called also gangliocytoma, ganglioglioneuroma, and ganglioma.

gan·glio·neu·ro·ma

(gang'glē-ō-nū-rō'mă),
A benign neoplasm composed of mature ganglionic neurons, in varying numbers, scattered singly or in clumps within a relatively abundant and dense stroma of neurofibrils and collagenous fibers; usually found in the posterior mediastinum and retroperitoneum, sometimes in relation to the adrenal glands.
Synonym(s): ganglioma

Ganglioneuroma usually occurs in the abdomen or thorax, but it can also occur in the head and neck region, with the latter being its least common location (6).
GD2 is a good diagnostic marker: it makes possible to differentiate neuroblastoma from benign ganglioneuroma and intermediate-grade ganglioneuroblastoma tumors that do not express or express this ganglioside at a low level.
Yearly surveillance upper endoscopy and lower endoscopy studies showed a colonic polypoid ganglioneuroma at 30 cm at age 10 and two additional distal colonic polypoid ganglioneuromas at age 12.
In animals, the ganglion cells of ganglioneuroma and ganglioneuroblastoma are strongly immunoreactive for neurofilament (KOESTNER & HIGGINS, 2002).
In addition, since gangliocytic paraganglioma has been reported by other names (e.g., ganglioneuroma [8], nonchromaffin paraganglioma [15, 16], and paraganglioma [17, 18]) until named "gangliocytic paraganglioma" by Kepes and Zacharias in 1971 [9] and becoming widespread, some GP cases were not identified in the first databases search.

Ganglioneuroma is a benign, slow-growing tumor originating from the sympathetic chain.
* Tumours with variable expression of receptors: insulinoma, phaeochromocytoma, paraganglioma, neuroblastoma, ganglioneuroma and medullary thyroid carcinoma.
Ganglioneuroma are rare, benign neural tumor of sympathetic nervous system originating from neural crest sympathogonia.
There are 3 kinds of histopathological patterns of neuroblastic tumours: neuroblastoma, ganglioneuroblastoma, and ganglioneuroma. Mizuno and colleagues (3) believed that a ganglioneuroblastoma had intermediate malignant potential and was less aggressive than a neuroblastoma.
On upper abdominal magnetic resonance imaging (MRI), a mass with a dimension of 4 cm was found in the right surrenal gland which suggested primarily neuroblastoma or ganglioneuroma (Figure 2).
