Are all pituitary tumors created equal?
No. There are more than a dozen very different disorders that result from pituitary tumors and disease. For example, if a tumor forms in an ACTH secreting pituitary cell, it could result in the overproduction of cortisol (Cushing’s Disease) or the underproduction of cortisol (adrenal insufficiency, often referred to as Secondary Addison’s Disease). Cushing’s is a condition characterized by excessive fat accumulation in central parts of the body (obesity, including a rounded or fat-filled face), diabetes, hypertension, a low serum potassium, thinning and bruising of skin, and osteoporosis. Symptoms of adrenal insufficiency include dehydration, low blood pressure and sodium level, and excessive weight loss. Primary Addison’s Disease is caused when the adrenal glands fail to work on their own, i.e. fail to respond to directions from the pituitary and hypothalamus. If the tumor forms in a growth hormone producing cell, it can overproduce growth hormone. Tumors that form from growth hormone
