Extra-adrenal pheochromocytoma.

We have presented our experience in the diagnosis and management of three patients with extra-adrenal pheochromocytomas. Only two had hypertension, although all three had increased catecholamine production. The third patient was normotensive preoperatively and remained normotensive after the immediate postoperative period. Two patients are alive and without evidence of disease, the third patient died from what was considered to be a malignant pheochromocytoma. All three patients presented with palpable masses, confirmed by computerized tomography.
