A pheochromocytoma (also phaeochromocytoma, English spelling) is a tumor of the medulla of the adrenal glands originating in the chromaffin cells, which secretes excessive amounts of catecholamines, usually epinephrine and norepinephrine. Extra-adrenal paragangliomas (often described as extra-adrenal pheochromocytomas) 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.
Inheritance
Up to 25% of pheochromocytomas may be familial. Mutations of the genes VHL, RET, NF1, SDHB and SDHD are all known to cause familial pheochromocytoma/extra-adrenal paraganglioma.
Features
The signs and symptoms of a pheochromocytoma are those of sympathetic nervous system hyperactivity:
- elevated heart rate
- elevated blood pressure. A clue to the presence of phaechromocytoma is the postural fall of systolic blood pressure greater than 10 mmHg on making the patient stand.
- palpitations
- anxiety often resembling that of a panic attack
- diaphoresis
- headaches
