Pankreatoblastoma

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 is characterized by multiple lines of differentiation (acinar, ductal, mesenchymal, neuroendocrine) and the presence of squamoid nests.
