description: A paraganglioma arising from the chromaffin cells of the paraganglia that are located along the sympathetic nerves.  It includes extra-adrenal paragangliomas and paragangliomas that arise from the adrenal medulla.  The latter are commonly referred to as pheochromocytomas.  Representative examples of extra-adrenal sympathetic paragangliomas include the bladder, and superior and inferior paraaortic paragangliomas.  Clinical signs are related to the secretion of catecholamines resulting in hypertension.
