A rare neoplastic gastroenterologic disease most often found in children, which usually presents with the non-specific symptoms of a palpable mass, vomiting, abdominal pain, jaundice, and weight loss/failure to thrive. Histologically, this malignant epithelial pancreatic neoplasm of the exocrine cells has multiple lines of differentiation (acinar, ductal, mesenchymal, neuroendocrine) and the presence of squamoid nests. Pancreatoblastoma can occur in any part of the pancreas. It is a malignant embryonal neoplasm that seems to recapitulate the embryogenesis of the pancreas, presumably because it originates from the pluripotent pancreatic stem cells during foregut development.
