The numerous case reports of pheochromocytoma emphasize its frequent association with either paroxysmal or sustained hypertension.Historical BackgroundFraenkel,1 in 1886, reported the case of an eighteen-year-old girl in whom autopsy showed bilateral adrenal tumors that probably were pheochromocytomas. Thirty-six years later Labbé, Tinel and Doumer2 presented the first adequate clinical description of the hypertensive crises associated with this lesion. Mayo,3 (1927) is credited with the first successful operative removal . . .
