[Malignant pheochromocytoma].

A case of metastatic malignant pheochromocytoma which was operated on is discussed. The benefits derived from the most recent localizing techniques such as CT scan and MIBG scintigraphic scanning are stressed. In the case presented these enabled the adrenal tumor to be detected but also demonstrated the presence of a costal metastasis and two metastases in the axial skeleton. A therapeutic trial with MIBG at doses of 100 mCi per treatment only enabled a survival of a little more than one year to be achieved.
