Addison Disease is a Consequence of a Tumor of the Adrenal

Question

Addison disease is a consequence of a tumor of the adrenal medulla.

Accepted Answer

Addison disease (also called primary adrenal insufficiency) is caused by the destruction or dysfunction of the adrenal cortex, not the adrenal medulla (which is responsible for producing adrenaline). Tumors of the adrenal medulla can cause other conditions, such as pheochromocytoma, but not Addison disease.
