pheochromocytoma
Pheochromocytoma is a rare type of tumor that arises from cells in the adrenal glands, specifically the chromaffin cells which produce hormones in response to stress. This tumor can cause an overproduction of hormones that regulate heart rate, blood pressure, and other body functions. As a result, individuals with this condition may experience high blood pressure, rapid heartbeat, sweating, and other symptoms. While most pheochromocytomas are benign, in some cases they may be malignant and spread to other parts of the body.

Pheochromocytoma
A pheochromocytoma or phaeochromocytoma is a neuroendocrine tumor of the medulla of the adrenal glands, or extra-adrenal chromaffin tissue that failed to involute after birth and secretes high amounts of catecholamines, usually noradrenaline, and adrenaline to a lesser extent. Extra-adrenal paragangliomas are closely related, though less common, tumors that originate in the ganglia of the sympathetic nervous system and are named based upon the primary anatomical site of origin.
U.S. National Library of Medicine
Pheochromocytoma
A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.
