A benign tumor of the adrenal medulla

Question

Quizplus · Accepted Answer

A benign tumor of the adrenal medulla is called a pheochromocytoma. It can cause symptoms such as high blood pressure, headaches, and sweating, but is not typically life-threatening unless left untreated or if the tumor becomes malignant. It does not cause Addison's disease, which is characterized by low levels of adrenal hormones including cortisol, aldosterone, and androgens. Excess secretion of cortisol is typically associated with other conditions such as Cushing's syndrome, and is not directly caused by a tumor of the adrenal medulla.
