A 14-year-old girl was admitted to our hospital because of left hip joint pain due to a pelvic mass. She was diagnosed as having Ewing’s sarcoma of the left pubic bone with distant metastasis to the right femur and left ischium on the basis of imaging and tumor biopsy findings. The primary lesion was removed after chemotherapy. Since metastasis remained and postoperative pelvic irradiation was required, laparoscopic right ovarian transposition was performed at the same time to preserve endocrine function. The whole tumor was resected macroscopically. Histopathological findings showed microscopic tumor remnants in part. On the 9th postoperative day, chemotherapy was resumed. Pelvic irradiation (total, 50.4 Gy) was initiated on the 16th postoperative day. Nine months after surgery, normal E2 and FSH levels were found. Multiple relapses were observed in the thoracolumbar vertebrae at 14 months postoperatively. Chemotherapy was resumed, but she died 25 months after surgery.
