[Malignant pheochromocytoma of the adrenal gland. Diagnosis 14 years after an incidental discovery of a contralateral pheochromocytoma].

The authors present a case of malignant adrenal phaeochromocytoma incidentally discovered 14 years after a similar finding in the controlateral adrenal gland. The rarity of incidentally discovered malignant adrenal phaeochromocytoma (second report in the literature) and the importance of isotope scan with MIGB for the investigation of asymptomatic and nonfunctioning phaeochromocytomas are outlined.
