Abstract

Hepatoblastoma is the most common primary malignant hepatic tumor except leukemia in infant and childhood. Some degree of confusion still exist because of the considerable variation in histologic structure and complexity. Recently, we experienced a case of hepatoblastoma in a seven wonts old female patient with chief complaints of palpable mass on abdomen and night sweating for 3 days. Positive findings are reveled as follows : a) Hemoglobin 6.9㎎/dl, T-bilirubin 4.5㎎/dl, LDH 720 μ/㎖ b) Alpha-fetoprotein 400 ng/㎖(↑) c) Simple abdomen: mass crossing midline in upper abdomen I.V.P. : Large Mass in upper abdomen and enlarged liver d) Ultrasono : Semisolid marts in liver parenchyme So left hepatectomy was done. Grossly, the tumor is rather firm, lobulated and well circumscribed measuring 11×10×7㎝ in dimension and 520 gm in weight. Cut surface stows pale grayish in color with areas of multifocal hemorrhagic areas. Microscopically, the tumor composed of m mainly solid cord of dark stained hepatocytes, pale stained cells, osteiod components and intermingled with extramedullary hematopoiesis. So was diagnosed as mixed type of hepatoblastoma according to Ishak and Glunz classification. Brief review of literature to this case was done.
