Hypertension is an extremely common diagnosis today. This condition can be caused by a multitude of factors, and can inversely cause numerous unfavorable processes in the body. One rare but significant source of hypertension is a tumor known as a pheochromocytoma, or PCC. This usually benign tumor is most often located on an adrenal gland, and can have a grave impact on the cardiovascular system. The tumor intermittently secretes an excess of the catecholamine norepinephrine, and if large enough, also secretes epinephrine . These episodic bursts can cause extreme hypertension and tachycardia, leading to, at times fatal results. By understanding the pathophysiology and clinical presentation of a pheochromocytoma, this tumor can be considered as part of the early differential diagnoses by the advanced practice nurse. If a detailed history is obtained, the PCC patient can be treated appropriately and a potentially tragic outcome may be avoided. Surgical intervention is the most successful treatment modality, if the patient has been deemed a good candidate . Careful monitoring must be performed pre-, during, and after surgery, noting any changes in vital signs or mental status. Pertinent patient education must be provided regarding significant symptoms, lifestyle modifications and when to seek immediate medical attention.
