We report a case of composite pheochromocytoma in a 53-year-old woman, with a 4-year medical history of uncontrolled hypertension without hypokalemia and treated with three antihypertensive. A computed tomographic scan was performed, showing the presence of a spontaneously hypodense adrenal mass of 6 x 6 x 3 cm at the expense of the outer arm of the right adrenal gland, and with microcalcifications and a double component. Laboratory studies showed elevated urinary metanephrines. Diagnosis of pheochromocytoma was retained. The patient underwent surgery and pathologic examination concluded the presence of a composite pheochromocytoma. http://pubs.sciepub.com/ajmcr/7/12/2/ajmcr-7-12-2.pdf hypertension hypokalemia adrenal gland composite pheochromocytoma ganglioneuroma
