Surgical Management of a Giant Pheochromocytoma.

Pheochromocytomas are rare tumors arising from chromaffin cells of the adrenal medulla and extramedullary sympathetic ganglia. The incidence of asymptomatic disease is rising due to increased detection rates from widespread use of computed tomography. We describe a case of one of the largest documented pheochromocytomas resected in the United States, an 18-cm tumor in a patient who presented with exertional dyspnea, abdominal pain, constipation, weight loss, and intermittent hypertension. After biochemical and appropriate imaging workup, the patient underwent an open resection of the mass. Copyright
