Question

the adrenal gland tumor that causes excessive release of epinephrine and adrenaline, resulting in severe hypertension, is called:
a pheochromocytoma
b adenoma
c pancreatoma
d myeloma

Explanation:

• Pheochromocytoma: A tumor of the adrenal medulla (or other chromaffin tissue) that secretes excessive amounts of epinephrine (adrenaline) and norepinephrine, leading to severe hypertension.
• Adenoma: A benign tumor of glandular origin. For example, adrenal adenomas may secrete cortisol (causing Cushing's syndrome) or aldosterone (causing Conn's syndrome), but not primarily epinephrine/adrenaline to cause the described hypertension.
• Pancreatoma: A tumor of the pancreas. It is not related to the adrenal gland and secretion of epinephrine/adrenaline.
• Myeloma: A cancer of plasma cells (in the bone marrow). It has no relation to adrenal gland function or secretion of epinephrine/adrenaline.

Answer:

A. pheochromocytoma
