Cushing syndrome due to adrenal tumor

Definition:

Cushing syndrome is an endocrine system disorder that has several possible causes. This article discusses Cushing syndrome caused by too much production of cortisol due to an adrenal gland tumor.

Alternative Names:

Adrenal tumor - Cushing syndrome

Causes, incidence, and risk factors:

Cushing syndrome is caused by constant, high levels of cortisol, a stress hormone. The growth of a tumor on one of the two adrenal glands causes about 15% of all cases of Cushing syndrome. Adrenal tumors release cortisol.

Adrenal tumors may be benign (non-cancerous) or malignant (cancerous). Non-cancerous tumors that may cause Cushing syndrome include adrenal adenomas or micronodular hyperplasia. Adrenal carcinomas are cancerous tumors that may cause Cushing syndrome.

Adrenal tumors are rare. They may develop in anyone at any age, but are much more common in adults. They are found in women more often than men.
