Pheochromocytoma is an efficient catecholamine-secreting tumor of the adrenal gland medulla. Catecholamines include norepinephrine, epinephrine, and their derivatives. Symptoms of pheochromocytoma include flank skin, elevated heart rate, elevated blood pressure, anxiety, sweating, headache, and weight loss. Within normal limits, norepinephrine and epinephrine hormones are responsible for regulating the blood pressure and heart rate. Excess production of catecholamine due to pheochromocytoma is a reason for high blood pressure with life-threatening and potentially serious difficulties such as stroke and heart attack. Pheochromocytoma occurs most frequently in adults aged between 30 and 60 years. Pheochromocytomas are not life-threatening mostly, but have 10% chances of being cancerous. High blood pressure is the most significant symptom; however, excessive sweating, light-headedness, a fast and pounding pulse when standing, severe headache, rapid breathing, and other symptoms may also occur.
