title: Use of enzyme histochemistry in the diagnosis of pancreatoblastoma.
abstract: The macroscopic, light microscopic and ultrastructural findings in a case of pancreatoblastoma in a neonate are presented. No evidence for exocrine or endocrine secretion could be found by histochemistry, immunocytochemistry or electron microscopy. However, enzyme histochemical techniques to localize activity of 'glucose-6-phosphatase', acid phosphatase, esterase and esteroprotease supported both a pancreatic origin for the tumour and a biphasic pattern of differentiation.
