What is Hepatoblastoma and explain in detail?
Hepatoblastoma is a malignant liver cancer occurring in infants and children and composed of tissue resembling fetal liver cells, mature liver cells, or bile duct cells. They usually present with an abdominal mass.  The disease is most commonly diagnosed during a childs first three years of life. Alpha-fetoprotein (AFP) levels are commonly elevated, but when AFP is not elevated at diagnosis the prognosis is poor.

Signs and symptoms
Patients are usually asymptomatic at diagnosis. As a result, disease is often advanced at diagnosis.

Pathophysiology
Hepatoblastomas originate from immature liver precursor cells, are typically unifocal, affect the right lobe of the liver more often than the left lobe, and can metastasize. They are categorized into two types: "Epithelial Type" and "Mixed Epithelial / Mesenchymal Type."Individuals with familial adenomatous polyposis (FAP), a syndrome of early-onset colonic polyps and adenocarcinoma, frequently develop hepatoblastomas
