title: A ruptured retroperitoneal germ cell tumor with invasion into the duodenum: a case report.
abstract: We report a rare case of a retroperitoneal germ cell tumor in a 31 years old male who presented with an acute abdomen. He gave a six-months history of back pain and significant weight loss. Clinical examination and ultrasound of the testes didn't show any primary focus. Intraoperative findings showed a retrolperitoneal midline mass that has ruptured into the peritoneal cavity and has invaded into the duodenum. The final pathology revealed a yolk sac tumor. We present this rare case of a primary para-aortic extragonadal yolk sac tumor and the differential diagnosis of a retroperitoneal mass.
