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] However, ganglioneuromas themselves are fully differentiated neuronal tumors that do not contain immature elements. [2]

When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. They are rare tumors, with an overall estimated incidence of 1 in 300,000. [ 1 ] There is no test that determines benign from malignant tumors ; long-term follow-up is therefore recommended for all individuals with paraganglioma.
An adrenal tumor or adrenal mass [2] is any benign or malignant neoplasms of the adrenal gland, several of which are notable for their tendency to overproduce endocrine hormones. Adrenal cancer is the presence of malignant adrenal tumors, and includes neuroblastoma , adrenocortical carcinoma and some adrenal pheochromocytomas .
Adrenal gland; the medulla (center, red) is the origin of the pheochromocytoma. There is an adrenal gland, highlighted in yellow, on top of each of the kidneys. Other clinical manifestations that have been reported include (in no particular order): [6] [13] Pallor; Heat intolerance; Weight loss; Chest and/or abdominal discomfort; Palpitations ...
An adrenocortical adenoma or adrenal adenoma is commonly described as a benign neoplasm emerging from the cells that comprise the adrenal cortex. Like most adenomas , the adrenocortical adenoma is considered a benign tumor since the majority of them are non-functioning and asymptomatic .
Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [1] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction. The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms.
Adrenocortical carcinoma (ACC) is an aggressive cancer originating in the cortex (steroid hormone-producing tissue) of the adrenal gland.. Adrenocortical carcinoma is remarkable for the many hormonal syndromes that can occur in patients with steroid hormone-producing ("functional") tumors, including Cushing's syndrome, Conn syndrome, virilization, and feminization.
