Paraganglioma (PG), also known as extra-adrenal pheochromocytoma, is a rare neuroectodermal tumor. The incidence of extra-adrenal paraganglioma is between 00.1-0.1%. Paragangliomas originating from the retroperitoneum are generally functional. 40-50% of them are malignant and they generally have a slow progression. Surgical resection and radiotherapy are the preferred methods for the local treatment of these tumors. A case with a tumor localized in the retroperitoneal space that was totally resected by surgical method was evaluated.
