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 ...
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.
Additionally, adrenal tumors that are larger than 4 centimeters in size, regardless of whether they produce hormones, also require adrenalectomy due to increased risk of adrenal cancer. Rarely (5–12%), the adrenal tumor may be cancerous (adrenocortical carcinoma), requiring adrenalectomy. Rarer still, the mass may be a metastatic cancer that ...
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.
Multiple endocrine neoplasia type 2 (also known as "Pheochromocytoma (codons 630 and 634) and amyloid producing medullary thyroid carcinoma", [1] "PTC syndrome," [1] and "Sipple syndrome" [1]) is a group of medical disorders associated with tumors of the endocrine system.
Treatment of PC12 cells with dexamethasone differentiates them into chromaffin-like cells. Using patch clamp recording and amperometry , there was a significant increase in quantal size, excitability and coupling between calcium channels and vesicle release sites, increasing from ~2x10 −19 to ~6.5x10 −19 moles.
It was initially isolated in 1993 from a pheochromocytoma, a tumor of the adrenal medulla: hence the name. [5] In humans ADM is encoded by the ADM gene. ADM is a peptide expressed by all tissues, and found in the circulation. A similar peptide named adreomedullin2 was reported in rats in 2004 which exhibits a similar function. [6]
