Pheochromocytoma is a rare tumor of adrenal gland tissue. It results in the release of too much epinephrine and norepinephrine, hormones that control heart rate, metabolism, and blood pressure.
Chromaffin tumors; Paraganglionoma
Pheochromocytoma may occur as a single tumor or as more than one growth. It usually develops in the center (medulla) of one or both adrenal glands. The adrenal glands are two triangle-shaped glands. One gland is located on top of each kidney. In rare cases, a pheochromocytoma occurs outside the adrenal gland. When it does, it is usually somewhere else in the abdomen.
Very few pheochromocytomas are cancerous.
The tumors may occur at any age, but they are most common from early to mid-adulthood.
In few instances, the condition may also be seen among family members (hereditary).
Most people with this tumor have attacks of a set of symptoms, which happen when the tumor releases hormones. The attacks usually last from a few minutes to hours. The set of symptoms include:
As the tumor grows, the attacks often increase in frequency, length, and severity.
Other symptoms that may occur include:
Treatment involves removing the tumor with surgery. It is important to stabilize your blood pressure and pulse with certain medicines before surgery. You may need to stay in the hospital and have your vital signs closely monitored around the time of surgery. After surgery, your vital signs will be continuously monitored in an intensive care unit.
When the tumor cannot be surgically removed, you will need to take medicine to manage it. A combination of medicines is usually needed to control the effects of the extra hormones. Radiation therapy and chemotherapy have not been effective in curing this kind of tumor.

Most people who have noncancerous tumors that are removed with surgery are still alive after 5 years. The tumors come back in some people. Levels of the hormones norepinephrine and epinephrine return to normal after surgery.
Continued high blood pressure may occur after surgery. Standard treatments can usually control the high blood pressure.
People who have been successfully treated for pheochromocytoma should have testing from time to time to make sure the tumor has not returned. Close family members may also benefit from testing, because some cases are inherited.
