Hypertension in patients with pheochromocytoma.
Adrenal-dependent hypertension syndromes are uncommon forms of hypertension. They include primary aldosteronism, pheochromocytoma, Cushing"s syndrome, and congenital adrenal hyperplasia. Pheochromocytomas are the cause of hypertension in 0.1% to 0.2% of hypertensive patients. Excess catecholamine release and other neural and humoral mechanisms contribute to the pathophysiology of hypertension. Patients with pheochromocytomas have a potentially curable cause of endocrine hypertension and, if undetected, pheochromocytomas confer a high risk for morbidity and mortality, especially during surgical procedures and pregnancy. All patients with incidental adrenal tumors, regardless of tumor size, should be biochemically screened for pheochromocytoma (especially before resection or needle biopsy) to avoid precipitation of a lethal hypertensive crisis.
