What is ?cushing's disease?

Cushing's DISEASE: Cushing's syndrome is any conditions that cause the adrenal gland to produce too much cortisol. Cushing's disease is a adenoma (tumor) in the pituitary that produces a hormone called acth which causes the adrenal gland to produce too much cortisol.

Pituitary ACTH: Cushings syndrome is a clinical syndrome produced by excess cortisol in the body. Cushings disease is one of the potential causes of the syndrome in which a benign pituitary tumor secretes an excess of acth (adrenocorticotropic hormone) this stimulates adrenal secretion of excess cortisol and produces cushings syndrome.
