A 25-year-old man admitted for abdominal pain and fever was found in blood tests to have inflammation and high AFP tumor markers. Abdominal computed tomography (CT) showed a 5 cm tumor above the inferior mesenteric artery (IMA) with one swollen lymph node para aorta. We conducted surgery under a diagnosis of retroperitoneal abscess. The tumor was located around the IMA, and resected. The definitive pathological diagnosis was retroperitoneal yolk sac tumor (YST). One month after surgery, he was found by CT to have recurrence. We started chemotherapy. The patient had no evidence of recurrence in the 6 months after chemotherapy. The key in treating this disease is early diagnosis followed by early chemotherapy.
