Abstract

Introduction: Yolk sac tumor (YST) is a malignant germ cell tumor with 10-15% arising in extragonadal sites. Methods: A search through our institution's database from January 01, 1990, to December 31, 2020, for "yolk sac tumor" or "endodermal sinus tumor" and "liver". Results: Our search yielded three cases. A 20-month-old girl with a liver mass and serum alpha-fetoprotein (AFP) level of 46558.0 ng/mL. The neoplasm was papillary with Schiller-Duval bodies. A 2-year-old boy with hepatic masses and adrenal mass with a serum AFP of 106,604.5 ng/mL. Numerous Schiller-Duval bodies were present. A 7-month-old girl with a liver mass, lung nodules, and retroperitoneal masses. Serum AFP was in the 800s ng/mL. Hepatoid and microcystic YST were mixed with hepatoblastoma (HBL). All three cases were positive for CAM5.2, SALL4, Glypican-3, beta-catenin, and AFP. Conclusion: Hepatic yolk sac tumor should be considered in the differential of a liver mass in pediatric patients with elevated AFP.

期刊介绍： Fetal and Pediatric Pathology is an established bimonthly international journal that publishes data on diseases of the developing embryo, newborns, children, and adolescents. The journal publishes original and review articles and reportable case reports. The expanded scope of the journal encompasses molecular basis of genetic disorders; molecular basis of diseases that lead to implantation failures; molecular basis of abnormal placentation; placentology and molecular basis of habitual abortion; intrauterine development and molecular basis of embryonic death; pathogenisis and etiologic factors involved in sudden infant death syndrome; the underlying molecular basis, and pathogenesis of diseases that lead to morbidity and mortality in newborns; prenatal, perinatal, and pediatric diseases and molecular basis of diseases of childhood including solid tumors and tumors of the hematopoietic system; and experimental and molecular pathology.
