An extra-adrenal pheochromocytoma mimicking a primary liver cancer

Abstract

Despite doctors’ every effort to be vigilant when diagnosing, sometimes a preoperative diagnosis is disproved by postoperative pathological examination. A patient was diagnosed with hepatocellular carcinoma and received surgery as treatment. On operation, a solitary retroperitoneal mass rather than a liver lesion was seen. On histopathological examination, the retroperitoneal mass was found to be an extra-adrenal pheochromocytoma.
