Bottom Line
Pheochromocytoma is a tumor of the adrenal gland. The classic triad of symptoms of this rare condition is hypertension, sweating, and headache; approximately 30% of patients report significant anxiety and panic. Several medications, including tricyclic antidepressants, beta-blockers, and buspirone, can lead to false-positive results on the serum and urine metanephrines testing used to diagnose pheochromocytoma.
