Pheochromocytoma--the catecholamine dependent hypertension.
Pheochromocytoma is a unique type of hypertension caused by excessive production of catecholamines by the chromaffin tumor. Pheochromocytoma, a potentially life-threatening disease, is a rare cause of hypertension. The incidence varies from 0.1 to 0.8% of hypertensive population. The author's experience is based on 138 patients treated in one institution from 1956 to 1995. Hormonal activity of pheochromocytoma varies considerably, influencing the pattern, of blood pressure and the clinical symptoms. It is emphasized that different other humoral mechanisms may play a role in the pathophysiology of this type of endocrine hypertension. Biochemical tests and non-invasive localizing methods are essential for the definite diagnosis of pheochromocytoma. A great progress has been made in this respect during the last three decades. Surgical removal of the tumor is the only definite therapy with low morbidity and mortality.
