Ganglioneuroblastoma is a variant of neuroblastoma that is surrounded by ganglion cells. It can be difficult to diagnose. [1] Nodular ganglioneuroblastoma can be ...
Ganglioneuroma (occasionally called a "ganglioma") is a rare and benign tumor of the autonomic nerve fibers arising from neural crest sympathogonia (undifferentiated cells of the sympathetic nervous system). [1]
Microscopic view of stroma-rich ganglioneuroblastoma. On microscopy, the tumor cells are typically described as small, round and blue, and rosette patterns (Homer Wright pseudorosettes) may be seen. Homer Wright pseudorosettes are tumor cells around the neuropil, not to be confused with a true rosettes, which are tumor cells around an empty ...
The adrenal cortex is composed of three distinct layers of endocrine cells which produce critical steroid hormones.These include the glucocorticoids, which are critical for regulation of blood sugar and the immune system, as well as response to physiological stress; the mineralcorticoid aldosterone, which regulates blood pressure and kidney function; and certain sex hormones.
Malignant ectomesenchymoma (MEM) is a rare tumor of soft tissues or the CNS, which is composed of both neuroectodermal elements [represented by ganglion cells and/or well-differentiated or poorly differentiated neuroblastic cells such as ganglioneuroma, ganglioneuroblastoma, neuroblastoma, peripheral primitive neuroectodermal tumors – PNET ...
Surgery can be used to remove mass affected by tumorous cells. [2] The prognosis of the disease is more positive for adults than for children, who have a higher probability of having sequelae from the tumor. [1] [2] It is important to note that this classification term has been removed from the latest WHO classification of CNS tumors as of 2016.

Treatment for neurofibrosarcoma is similar to that of other cancers. Surgery is an option; the removal of the tumor along with surrounding tissue may be vital for the patient's survival. For discrete, localized tumors, surgery is often followed by radiation therapy of the excised area to reduce the chance of recurrence. For patients who have ...
