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.
