What are adrenal tumors?
Tumors of the adrenal glands are rare. However, when present, they can cause a multitude of disorders by excessively secreting certain adrenal-produced hormones. One type of tumor of the adrenal glands is called a pheochromocytoma.
What is a pheochromocytoma?
A pheochromocytoma is a benign adrenal gland tumor that secretes epinephrine and norepinephrine hormones. These hormones are responsible for regulating heart rate and blood pressure, among other functions. Pheochromocytomas occur most frequently in young to middle-aged adults between the ages of 30 and 60.
What are the symptoms of pheochromocytoma?
The most common symptom of pheochromocytoma is high blood pressure, which is sometimes extreme. Other symptoms are usually nonexistent, unless the person experiences pressure from the tumor, emotional stress, changes in posture, or is taking beta-blocker drugs for a heart disorder.

Treatment for pheochromocytoma
Treatment for pheochromocytoma usually includes removing the tumor. Before removing the tumor, however, your physician may prescribe drugs to control high blood pressure.
Rarely pheochromocytomas can be malignant and may metastasize to other organs. Chemotherapy following resection of the primary tumor is the treatment of choice for malignant pheochromocytomas.
