[Hepatoblastoma in children].

Five observations of hepatoblastoma in boys of 10 months to 4 years of age are presented. Tumor mass in the right part of the abdominal cavity was detected 1--9 months before death. Three patients died of pulmonary cardiac insufficiency, 2 of cateterization sepsis and hepatic insufficiency. The liver weight varied from 840 to 3500 g. Two children had intrahepatic metastases, one of them also had extrahepatic metastases into the portal lymph nodes and lungs. In 2 observations hepatoblastoma was of an epithelial structure, in 3 cases of a mixed type. It is suggested that hepatoblastoma, as well as liver carcinoma in adults, occurs more frequently in males.
