Combined hepatoblastoma and yolk sac tumor of the liver.
The authors report a liver tumor that occurred in a 6-month-old boy in which areas of yolk sac and hepatoblastoma were identified. To the best knowledge of the authors, this morphologic pattern has not been reported previously. Theories of histogenesis are discussed.
