What determines mortality in malignant pheochromocytoma? - Report of a case with eighteen-year survival and review of the literature

SUMMARY Pheochromocytoma (PCC) is a tumor derived from adrenomedullary chromaffin cells. Prognosis of malignant PCC is generally poor due to local recurrence or metastasis. We aim to report a case of malignant PCC with 18-year survival and discuss which factors may be related to mortality and long-term s...
