Paraganglioma and adrenal pheochromocytoma presenting simultaneously in an elderly female. Case report and review of the literature.

ABSTRACT

Paragangliomas are chromaffin tissue tumors arising in an extra-adrenal location. It is quite rare to find a paraganglioma concurrently with a pheochromocytoma. We report a patient who underwent resection of a retroperitoneal mass that was characterized pathologically as a malignant paraganglioma. An incidental finding was a microscopic pheochromocytoma in the ipsilateral adrenal gland.
