It is the most common malignant germ cell tumor in the pediatric population. It occurs in the infant testis, ovary, sacrococcygeal region, vagina, uterus, prostate, abdomen, liver, retroperitoneum, thorax, and pineal/third ventricle. The tumor mimics the yolk sac of the embryo and produces alpha-fetoprotein (AFP). Treatment includes: surgical resection, radiation, and chemotherapy. This tumor is very responsive to chemotherapy regimens that include cisplatinum.NCI" . . _:b723984 . _:b795952 _:b723982 . "An unusual and aggressive tumor of germ-cell origin that reproduces the extraembryonic structures of the early embryo. It is the most common malignant germ cell tumor found in children. It is characterized by a labyrinthine glandular pattern of flat epithelial cells and rounded papillary processes with a central capillary (Schiller-Duval body). The tumor is rarely bilateral. Before the use of combination chemotherapy, the tumor was almost invariably fatal. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1189)MSH2003_2003_05_12" . . _:b723983 .
