A pheochromocytoma is a challenging tumor to recognize and one that can be most gratifying for the physician as he sees a clinical cure result from its removal. It is a chromaffin cell tumor, most often found arising from the adrenal medulla, but one that may develop wherever chromaffin tissue is found, as in the paraganglia of the sympathetic nervous system. There is no difference in sex distribution,1 although a familial incidence has previously been noted.2, 3 The tumor is more commonly found in the right adrenal gland. Approximately 10% are bilateral; a similar percentage is malignant.1
