title: [Adenocarcinoid of the stomach. Histochemical and immunohistochemical study using optical and electron microscopy].
abstract: A case of gastric adenocarcinoid was described by light and electron microscopy and immunohistochemistry. The tumor contained exocrine, endocrine and amphicrine cells. In endocrine cells, serotonin and pancreatic polypeptide were demonstrated. It was suggested that these gastric adenocarcinoid cells originate from totipotent immature cells of endodermal origin.
