Abstract
A case of a malignant phenochromocytoma of the organ of Zuckerkandl is reported. There was a solitary functional metastasis in the left femur, which was treated by hip disarticulation after removal of the primary. The patient is asymptomatic and free of further metastases after 3 years. Other reported cases of solitary metastases from malignant pheochromocytomas are cited. These occurred most frequently in the skeleton system, which is the most common site of distant metastases in malignant pheochromocytoma. The reported case and the review of the literature indicate that solitary or limited metastatic lesions should be treated surgically by partial or, when possible, complete resection.
