Hepatoblastoma

Comments:
Hepatoblastoma is typically a solitary, well-demarcated mass arising in noncirrhotic liver parenchyma. As in hepatocellular carcinoma, hemorrhage, necrosis, and bile-staining may be prominent. Almost all hepatoblastomas express alpha fetoprotein. There is marked size variation as tumors often present late with non-specific symptoms. Multinodular tumors may contain different histologic components and should be adequately sampled. Following chemotherapy, there is often abundant necrosis and only mesenchymal components may remain viable.
