A '''pheochromocytoma''' ('''phaeochromocytoma''' outside of the US) is a [[neuroendocrine tumor]] of the [[Adrenal medulla|medulla]] of the [[adrenal gland]]s (originating in the [[chromaffin cell]]s) or extra-adrenal chromaffin tissue which failed to involute after birth,<ref>{{cite book |author=Boulpaep, Emile L.; Boron, Walter F. |title=Medical physiology: a cellular and molecular approach |publisher=Saunders |location=Philadelphia |year=2003 |pages=1065 |isbn=0-7216-3256-4 |oclc= |doi=}}</ref> which secretes excessive amounts of [[catecholamine]]s, usually [[epinephrine]] and [[norepinephrine]].
Extra-adrenal [[paragangliomas]] (often described as extra-adrenal pheochromocytomas) are closely related, though less common, tumors that originate in the [[ganglion|ganglia]] of the [[sympathetic nervous system]] and are named based upon the primary anatomical site of origin.
