Liver transplantation is a well-established treatment for liver failure and for a selected group of patients with hepatic tumors. The growing teratoma syndrome refers to the phenomenon whereby germ cell tumors enlarge after chemotherapy despite complete eradication of malignant cells and normalization of serum tumor markers. We present the case of a young patient with rapidly growing teratomatous masses in his liver who was treated with liver transplantation from a live donor. We discuss his postoperative management, follow-up, and briefly review literature on the subject.
