Signs and symptoms of pheochromocytomas may include:
High blood pressure
Rapid heart rate
Forceful heartbeat
Profound sweating
Abdominal pain
Sudden-onset headaches — usually severe — of varying duration
Anxiety
Feeling of extreme fright
Pale skin
Weight loss

These signs and symptoms develop because this type of tumor produces an excess of chemical compounds called catecholamines. Excessive secretion of catecholamines — the hormones adrenaline (epinephrine) and noradrenaline (norepinephrine) — can lead to persistent high blood pressure or wild fluctuations in your blood pressure, depending on whether the catecholamines are released continuously or in shorter bursts. The intermittent release of these hormones can cause other symptoms to occur from time to time as well.
