There are no definitive histological or cytological criteria of malignancy, as it is impossible to determine this condition in the absence of advanced local regional disease or metastases. This is a case report of 46 year old patient with giant retreperitoneal mass. The patient was a known case of hypertension. The USG-guided FNAC reported the case as- Malignant Neuroendocrine tumor-possibly pheochromocytoma/ paraganglioma. CECT reported the mass as retroperitoneal neoplasm. The VMA levels in urine were raised 3 folds. Surgery was performed and histopathological report suggested features of-Pheochromocytoma.
