title: Multiple hepatoblastomas associated with trisomy 18 in a 3-year-old girl.
abstract: A very rare case of full trisomy 18 associated with multiple hepatoblastomas is reported. The patient also had ventricular septal defect and patent ductus arteriosus, which were repaired at 6 months of age. After the cardiac surgery, she was noted to have an abdominal mass and an elevated serum alpha-fetoprotein level. A partial hepatic lobectomy was performed at 7 months of age, and the resected tumor was diagnosed as a fetal-type hepatoblastoma. At 2 years and 4 months of age, a chest radiography disclosed an elevated left diaphragm, and abdominal ultrasonography demonstrated a tumor in the left hepatic lobe. The resected tumor was also diagnosed as a fetal-type hepatoblastoma. Chromosomal analysis demonstrated that the karyotypes of peripheral blood and hepatic tumor cell obtained on two occasions were both 47,XX, +18. She has no evidence of recurrence at 3 years of age without specific therapy.
