2024年10月3日 · Ganglioneuroma is a mature, benign neoplasm of the adrenal gland that is composed predominantly of Schwannian stroma with admixed mature ganglion cells

Ganglioneuroma (GN) of the gastrointestinal tract is an extremely rare neuroectodermal tumor. Patients with ganglioneuromas have different presentations depending on the location, extent and size of the lesion. We present two cases of ...

The results of pathology review were analyzed with age at diagnosis, clinical stage, MYCN status, DNA ploidy pattern, primary tumor resectability, and clinical outcome of the patients.

Ganglioneuromas (GNs) are rare and benign neural tumors arising from the paravertebral sympathetic plexus and occasionally from other sites [1]. The most common site for GNs is the posterior mediastinum and the retroperitoneum [2].

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] Ganglioneuromas can be diagnosed visually by a CT scan, MRI scan, or an ultrasound of the head, abdomen, or pelvis.

Ganglioneuroma is a benign neuroblasic tumour. It is also known as ganglioma. [1] It should not to be confused with ganglioglioma. May be retroperitoneal. Occasionally found in the GI tract - may form colonic polyp. Multiple ganglioneuromas may be due to multiple endocrine neoplasia IIb. Classification: Ganglioneuroma (benign).

2025年1月24日 · Pathology. Like neuroblastomas and ganglioneuroblastomas, ganglioneuromas are derived from the primordial neural crest cells that form the sympathetic nervous system. Pathologically, they are composed of ganglion cells, Schwann cells and fibrous tissue.

GANGLIONEUROMA. It is a fully mature benign neoplasm of the sympathetic nervous system that usually occurs in older age group than Neuroblastoma; Discovered incidentally but may present with VIP syndrome; Age group-7 years of age or older; Site – Arises in posterior mediastinum followed by the retroperitoneum particularly the presacral space

2023年4月26日 · Ganglioneuroma is a rare type of non-cancerous tumour made up of cells normally found in the nervous system including ganglion cells, nerve fibers, and Schwann cells. What causes ganglioneuroma? Most people who develop a ganglioneuroma have no known risk factors and the cause remains unknown.

Ganglioneuroma is a benign neuroectodermal tumor composed of ganglion and Schwann cells. There are no immature neuroblastic elements. The most common sites of involvement are along the distribution of sympathetic nervous system and include posterior mediastinum, retroperitoneum, and adrenal gland.
