Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. Adrenal disorders may cause hyperfunction or hypofunction, and may be congenital or acquired.
Paraganglioma in patient with pheochromocytoma
A paraganglioma is a rare tumor that begins in certain nerve cells that are dispersed throughout the body. This tumor can affect people of any age but most often shows up between the ages of 30 and 50. The tumor is often slow growing and noncancerous (benign).
Pheochromocytoma is a rare tumor of adrenal gland tissue. It results in the release of too much epinephrine and norepinephrine, hormones that control heart rate, metabolism, and blood pressure.
About the Adrenal Gland
The adrenal gland produces hormones that affects growth, development and stress, and also helps to regulate kidney function. There are two parts of the adrenal glands, the adrenal cortex and the adrenal medulla. The adrenal cortex produces mineralocorticoids, which regulate salt and water balance within the body, glucocorticoids (including cortisol) which have a wide number of roles within the body, and androgens, hormones with testosterone-like function. The adrenal medulla produces epinephrine (adrenaline) and norepinephrine (noradrenaline). Disorders of the adrenal gland may affect the production of one or more of these hormones.
