title: Pancreatoblastoma. A histochemical and ultrastructural analysis.
abstract: A case of pancreatoblastoma in a 4-year-old boy is presented. This tumor was studied by histochemical and ultrastructural techniques and was found to have both exocrine and endocrine components. This analysis and a review of the literature helps to further define this entity, which has a significantly better prognosis than other pancreatic malignancies.
