Pheochromocytoma: a 10-year experience in a tertiary care North Indian hospital.
BACKGROUND
The study was carried out to highlight the clinical and biochemical profile of patients with pheochromocytoma in a tertiary care center of North India.


RESULTS
Thirty consecutive cases of pheochromocytoma admitted over a period of 10 years to our Institute were analyzed. The chief clinical complaints of these 30 patients (17 males and 13 females, mean age 24+/-7 years) were palpitation (80%), headache (77%), sweating (60%), breathlessness (67%) and flushing (56%). The clinical triad of headache, flushing and sweating occurred in 26.7% of cases. On clinical examination, 97% of the patients were hypertensive and 16.6% presented with malignant hypertension. Laboratory measurements showed that the levels of 24-hour urinary vanillylmandelic acid were elevated in 80% of cases. Levels of plasma adrenaline and noradrenaline were raised in 78% and 79% of cases, respectively. Anatomical localization of the tumor on computerized tomographic scan showed the presence of an adrenal tumor in 80% and extra-adrenal tumor in 20%. Surgical removal of the tumor could be carried out in 28 cases following control of the blood pressure with antihypertensive drugs including alpha and beta adrenoreceptor blockers.


CONCLUSIONS
Pheochromocytoma should be suspected in all young hypertensive persons. The appropriate therapy for this tumor is surgical removal preceded by adequate blood pressure control including the use of alpha and beta adrenoreceptor antagonists.
