Gastroblastoma is a malignant epithelial tumor of the stomach, which is primarily diagnosed based on its biphasic histomorphology and the demonstration of its characteristic molecular fusion gene, MALAT1-GLI1. Variability in the histomorphology has not been studied so far owing to its rarity. With very few cases reported in the literature, its long-term course is not entirely understood, with most of the cases treated based on its stage.
