title: Retroperitoneal lipoblastoma involving the right common iliac artery and vein.
abstract: A case of benign lipoblastoma of the retroperitoneum in a 12-month-old boy, presenting as a huge abdominal mass and right lower extremity swelling, was reported. Surgery revealed involvement of the right common iliac artery and vein by lipoblastoma, requiring the sacrifice of both vessels for complete removal of the tumour. Vascular continuity of both vessels was re-established by a saphenous vein graft interposition. Involvement of a great artery by benign lipoblastoma has not been reported before.
