Abstract
Hepatoblastoma (HB), rare malignancy in itself, is the most common primary liver tumor in children. Most common presenting features are abdominal distension or abdominal mass. Several patterns are associated with HB with different prognosis. Furthermore, some patterns have overlapping features with other childhood tumors. The aim of this study is to discuss various patterns of HB which we came across in a tertiary care hospital during our study. H and E slides were reviewed with respect to different patterns, postchemotherapy changes including extramedullary hematopoiesis, necrosis, osteoid metaplasia, necrosis, and fibrosis. Different patterns of HB should be kept in mind by the pathologists to avoid any misdiagnosis.
