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 .
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.
It is usually done to remove tumors of the adrenal glands that are producing excess hormones or is large in size (more than 2 inches or 4 to 5 centimeters). Adrenalectomy can also be done to remove a cancerous tumor of the adrenal glands, or cancer that has spread from another location, such as the kidney or lung.
Hence, the molecular mechanisms involved in normal development of the adrenal glands are like double edged swords that can lead to the formation of tumors within the adrenal cortex. Moreover, recent studies suggest that mutations affecting the molecular pathways of the adrenocortical region can stimulate abnormal proliferation and tumor formation.
Adrenal cancer is a "rare cancer that begins in one or both of the small, triangular glands (adrenal glands) located on top of your kidneys," according to the Mayo Clinic. Adrenal glands are ...
In the cases with underlying tumors, benign lesions including adrenal cyst and myelolipoma bigger than 10 cm may spontaneously bleed into the adrenal gland or retroperitoneum. Massive bleeding from a primary adrenal tumor could be fatal in up to half of the reported cases, which are most resulted from pheochromocytoma.
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 ...
