Hepatoblastoma in a Male Adult: Report of a Case

Hepatoblastoma is a rare malignant tumor of the liver, usually occurring in the first three years of life. Hepatoblastomas in adults are unusual and are an exceptional cause of primary malignant liver tumor in adult patients. An 84-year-old man suffered from progressively poor appetite and weight loss for 5 months. Magnetic resonance examination revealed a tumor was enhanced in the arterial phase and washed out in the late phase on dynamic studies. Hepatocellular carcinoma was diagnosed by the radiologists. Serum α-fetoprotein level was 8849 ng/ml. Subsequently, a S5 segmentectomy was performed. To our surprise, pathologic examination of the resected liver tumor confirmed the diagnosis of hepatoblastoma of a mixed epithelial and mesenchymal type with teratoid features. We concluded that hepatoblastoma should be included in the differential diagnostic list of malignant liver tumor in adults.
