PHAEOCHROMOCYTOMA

1. Pheochromocytomas are rare tumors that arise from chromaffin tissue, with symptoms due to secretion of catecholamines: epinephrine, norepinephrine, and dopamine.

2. 10% of pheos are extra-adrenal tumors that are called extra-adrenal paragangliomas - risk of malignancy is higher.

3. The differential diagnosis includes labile essential hypertension, anxiety, hyperthyroidism, hypoglyce­mia, menopausal flushing and carcinoid.
