This case report describes the clinical features, diagnosis, and management of a rare retroperitoneal PNET/EWS in an adult patient.
Alerts to perioperative risks in rare retroperitoneal PNET/EWS; leaves open optimal management approaches pending further evidence.
Primitive neuroectodermal tumor (PNET) and Ewing’s sarcoma (EWS) are small round cell tumors occurring mainly in children and adolescents, rarely in adults. It can occur in multiple tissues and organs including kidney, adrenal, bladder, liver, small intestine, colon and rectum, with a preferred location within the chest area, in the limbs and around the spine, but with rare cases of abdominal, pelvic or retroperitoneal. Here we present a case of the retroperitoneal PENT/EWS in a 38-year-old man and we discuss the clinical features, histopathological characteristics, diagnosis, treatment and prognosis.

Zhang et al. (2013) conducted a case report in Retroperitoneal primitive neuroectodermal tumor/Ewing's sarcoma (PNET/EWS) (n=1). Surgical resection and chemotherapy was evaluated. A 38-year-old man with a rare retroperitoneal PNET/EWS experienced rapid tumor growth and died of complications after a planned secondary surgery was aborted due to tachycardia.
