Characterized by high secretion of catecholamines, pheochromocytoma is a tumour that originates from pheochromocytes in the medullar portion of the adrenal glands.
Phenylethanolamine N-methyl transferase (PNMT), an enzyme localized in adrenal chromaffin cells and pheochromocytes, leads to the methylation onto the amino group of norepinephrine to produce epinephrine.
The adrenal medulla is located at the centre of the adrenal gland, is surrounded by the adrenal cortex, and consists of secreting cells called "chromaffin cells" (or pheochromocytes because they stain brown with chromium salts) that secrete epinephrine (adrenaline), norepinephrine (noradrenaline), and a small amount of dopamine in response to stimulation by sympathetic pre-ganglionic neurons [72].
